These tables assume that the secondary side of the transformer is protected at 125% of its full load current. This is usually the case.Fuses used on the primary side of transformers must be capable of:

n Withstanding the magnetizing inrush to the windings of approximately 12x the normal full load current of the primary for 0.1 sec. without operation or element damage.

n Carrying short-term overloads not exceeding 150% of the normal full load primary current.The fuse ratings recommended meet these requirements.

DAITO Alarm Indicating FusesDaito fuses are frequently used in machine tools, CNC and robotic equipment, telecommunications and equipment from Fanuc, Yaskawa, Toshiba and NEC.

They are AC/DC rated fuses with an integral alarm contact that is closed on fuse operation, signalling that the fuse has operated.

They are a unique size and cannot be interchanged with other fuse types. Other Daito designs as well as fuseholders available on request.

‘R’ Rated Motor FusesMVR fuses are current and energy limiting fuses intended for the backup protection of medium voltage motor control. They are non-venting.

MVR fuses have integral striker/indicators and have standardized dimensions compatible with today’s 5.5kV motor control gear. They are fully interchangeable with other manufacturers’ fuses of the same type and rating.

They feature a ‘field toughened’ element design which makes them less susceptible to mechanical damage during shipping and installation while also providing superior cycling characteristics.

MV R 5 / 09R - D I XYS

Installation Notes:

1. When replacing ‘R’ fuses, always replace with the same ‘R’ rating to maintain coordination and motor starting capability.

2. These fuses can replace any manufacturers’ fuse of same ‘R’ rating.

3. Ensure that fuse clips have good tension. (if you can spin the fuse in the clips easily, clips should be replaced.)

4. Clean all contact surfaces before installation.

5. Install with striker pin facing up.

6. Unless the cause of fuse failure is known to have been confined to 1 phase, fuses should be replaced in sets of 3 to ensure ‘As new’ performance.

R Rating Defined

The ‘R’ rating of a fuse is established by dividing the 20-35s melt current of the fuse by 100.

Fuses of the same ‘R’ rating will have the same time current characteristics and ensure identical motor starting performance and coordination with the overload relays.

Technical data presented.

Amp Rating

Each fuse has both an assigned ‘R’ and amp rating. It is the ‘R’ rating of the fuse that governs the motor starting capability and coordination with the overload relays. To maintain the same capabilities, fuses should be replaced with matching ‘R’ ratings.

On direct across the line starts, the necessity of passing the motor starting current results in a fuse selection with an assigned amp rating well above the nominal motor full load amps.

However, applications using reduced voltage starts, variable frequency drives or other methods to reduce the motor starting current, can result in a fuse rating with an amp rating too close to the motor F.L.A. As a check, the fuse’s assigned full load amp rating should be a minimum of 140% of the nominal full load amps of the motor.

Peak Let-thru Characteristics

Use these characteristics to evaluate busbar bracing requirements and withstand capability of down-the-line components.

Read RMS fault value on lower scale and read up to where it intersects the line for the fuse you are evaluating. From this intersection point, read across to the left hand scale to obtain the peak current let-thru. Note: this value is in peak asymmetrical amperes. To convert to RMS symmetrical, divide by 2.3. Peak let-thru graph is valid for all voltage classes.

Time current Characteristic curves.

Time current curves shown on pages 4-6 are minimum melting curves. For total clearing, please refer to the curves on pages 7-9.

Characteristic curves are generated with the fuse at an ambient temperature of 24-26 C. Ambient temperatures higher than 30 C may require fuse de-rating. Please contact Fusetek in this instance.

Motor Application Tables.

Standard duty is defined as: 2 evenly spaced starts per hour, 25o C ambient temperature, 10 second run-up time and a starting current of no more than 6X the nominal full load amp of the motor.

If any of these parameters are exceeded - use the heavy duty (HD) column.

Select the appropriate HP rating in the left column•

• Read across to the appropriate voltage and duty column (Std or HD)

Use the ‘R’ rating of fuse specified•

5.5kV fuses may be used on 2.3kV control.•

The graphic on the right is a screen shot from our free Fusesoft 5.0 fuse selection software and shows the ideal coordination between the fuse, overload relay and motor starting current. The motor starting tables were generated using this software. Fusesoft 5.0 can be downloaded at no charge by visiting www.fusetek.com

Features

n General purpose 'E' rated characteristics.n Pure silver elementsn Fully plated metal parts for cool running.n Excellent current limitation for substantial reduction of short circuit stresses.n Blown fuse indicator pin for visual indication or mechanical actuation (except 2" body)n All D Case 3" Diameter fuses can be hermetically sealed and supplied without indicator for use in hazardous location application.

Companion Products

Standoff insulators, fuse clips and bases. Please see accessories section in rear of this section. For other ratings and designs, please contact Fusetek.

Retrofitting

Fusetek power fuses are dimensionally compatible with and interchangeable with other manufacturers' fuses having the same dimensions and ratings. Standard 'E' rated characteristics ensure electrical equivalency.

Fuses should be replaced in sets of three to avoid nuisance blowing caused by element damage.

Tag Variations

3" diameter E rated fuses are available with the following options. Add the suffixes shown to the end of the part number - example;

X - 2" longer tube to line up with some manufacturers' longer bodies.Bi - Offset mounting brackets for bolt mounting.W - Hookeye disconnect feature.CL - ITE/Gould style clip-lock mounting.

E Rating Defined

100E or less:Fuse must open in 300sec at 200-240% of its rated current over 100E: Fuse must open in 600sec. at 220-264% of its rated current.

Thus, fuses with identical E ratings will provide similar overload protection and co-ordination with transformer and other protective devices.

E Rated Distribution fusesE rated power fuses are current limiting partial-range fuses usually used for fusing the primary windings of medium voltage distribution transformers and associated distribution circuits.

Their high degree of current limitation greatly reduces the thermal and mechanical stresses imposed on system components during a short circuit. They can be used indoors or outdoors in a suitable enclosure and conform to standard N. American dimensions.

DIN HV DistributionDIN HV fuses are partial-range high voltage current-limiting fuses for use in distribution circuits from 2.3 - 38kV.

Their compact dimensions and non-venting characteristics make them ideal for restricted enclosures. DIN HV fuses have excellent short circuit performance and good low overcurrent clearing capability. When used in combination with fusible switches with fuse-activated trip feature, full range clearing capability is achieved.

True full-range fuses are available in certain voltage and amp ranges. Please contact Fusetek for more information.

Features

n Highly standardised DIN 43 625 dimensions.n Excellent short circuit performance. Ceramic bodies, pure silver elements.n '30' series fuses have a temperature sensitive striker to protect against extended overload conditions, or

external overheating. n Sealed for indoor or outdoor use. n Striker pin can be used for visual indication or mechanical actuation of other devices. (Std-80N, HD - 120N)n High amp ratings available for larger installations. n Fully plated parts for cool running.

Installation Notes

1. DIN fuses are partial range devices with a minimum interrupting rating. Care must be taken to ensure thatanticipated currents below the fuse's minimum breaking current (m.b.c) are cleared by other devices. In thisregard, DIN fuses are similar to ANSI - 'E' rated fuses. Full range DIN fuses are available in limited voltageand amp ranges. Please contact Fusetek for information.

2. When DIN fuses are used in conjunction with a trip-all-phase-device, the minimum breaking capacity of the switch or contactor must be equal to or greater than the m.b.c of the fuse.

3. Maximum voltages listed are absolute maximums for safe operation. Utility system tolerances on voltagemust be considered when selecting a voltage range.

4. When replacing fuses in the field, ensure that contact clips are clean and free of corrosion, dirt, grease etc. Ensure that the fuse clips still have good tension. (if the fuse will spin easily in the fuse clips, the clips havelost their tension and should be replaced)

5. Fuses should be replaced in sets of three to avoid nuisance blowing caused by element damage.

33

Dimensions

All DIN fuse share common end fittings which fit into 45mm fuse clips. The only dimensional variables are the body length (L) and body diameter (D). As this varies depending on voltage, amperage and other factors, please refer to the tables in this section for D and L dimensions. Striker pins meet industry and DIN requirements for force/travel and can be used for mechanical actuation or visual indication.

Transformer application

The fuse ratings recommended in the following tables have been chosen with the following conditions in mind:

n Fuses must pass normal primary winding magnetising inrush currents: These are taken as 12x the normal full load current (FLC) at .1 sec, and 25x FLC at .01 sec. Certain applications may require the use of a higher fuse rating. Please contact FUSETEK with application details.n After a sustained power outage, the fuse must be able to withstand an overload of approximately 6 x FLC for 1 sec. and 3 x FLC for 10 sec.n The maximum voltage rating of the fuse must be equal to, or greater than the maximum line-to-line system voltage.

Capacitor application

Refer to capacitor selection chart on page 27. Be sure to consider the switching options and proximity of other banks when establishing a base FLC to apply. Fuses used on Capacitor fuses should be rated at 150% of system voltage.

TFCF 600V Capacitor fusesTFCF fuses are current limiting fuses designed for the unit fusing of 600v (or less) capacitors. They are threaded for M12 metric capacitor bushings, but may be adapted to other thread patterns with the adapters shown elsewhere in this publication.

n Metric threaded for direct screw on mounting to metric capacitor studs.n Excellent short circuit performance.n Fully plated metal parts for cooler running.

TFCF fuses should be selected at 250-300% of the nominal capacitor full load current or next nearest size up. If capacitor is installed in close proximity to other capacitor banks, or is switched frequently, select higher amp fuses within this range.

Fuse Selection chart for Capacitor fuses

Applicable for all current limiting fuses - high and low voltage. Use dotted line for single phase and star connections, solid line for delta connections. Above 100A, curves are identical.

For auto-switching, or switching in close proximity to other capacitor banks, multiply capacitor FLA x 1.6 before using scale at bottom. Read up from capacitor FLA scale at bottom to intersection of appropriate curve (star or delta). Fuse rating is whatever band intersection occurs in. Read fuse rating on left scale.

KF22-12 HV IndicatorThe KF22-12 is a solid state device that signals the presence of system voltage by flashing an array of 3 high brightness red LED’s.

The KF22-12 works on the principle of capacitively coupling the device through air to ground, so there is no high voltage wiring or clearance issues.

n mounts directly to live partsn flashing LED is easy to see.n Solid state design for long lifen Compact dimensionsn No maintenance requiredn One model does all service voltages

HV Indicators for remote signallingOur microswitch assembly allows remote annunciation of fuse operation. It consists of an insulated Bowden cable operating a microswitch. One end of the cable is terminated in a bracket at the fuse end, the other terminating in a bracket that also houses the microswitch. The actuating force is provided by the fuse striker pin.

n Provide remote annunciation of fuse operation (per phase.)n Easily adaptable to a variety of clip/fuse configurations.n No maintenance requiredn Standard Form C NO/NC contacts.

DIN 43 625 UltrafastSquare body rectifier fuses are used in large drives and power conversion equipment where larger amp ratings and superior short circuit performance are required. SIBA UR fuses are fully compatible with other manufacturers' fuses.

n Integral blown fuse indicator and microswitch bracketn extremely low levels of energy let-thrun N. American and European pattern dimensionsn approved

DIN 43625 fuses come in 5 case sizes - 000, 00, 1, 2, & 3. Within these case sizes - UR fuses come in two voltage ratings (700 & 1300Vac) and two fixing centers (80 and 110mm). These fuses can easily be fitted with a microswitch for remote annunciation, or may be used without this option.

DC Application

URS series fuses can be used on DC circuits with voltage levels dictated by the time constant of the circuit (l/r). Shorter time constants are easier duty on the fuse and so higher DC voltages can be toler-ated. Usually, time constants are 20ms or less.

Refer to the chart at right to get the equivalent working DC voltage once the time constant is known.
