    © When operation of the controller requires jogging (inching) or plug stopping or when normal operation requires continued operation in excess of 5operations per minute or 10 operations in a 10-minute period, the plugging or jogging horsepower ratings must be followed.

    ® In lieu of a 500 to 1500 VA control transformer, a 50 VA unit in conjunction with a control relay can be used as follows:1. Wire control relay coil in control circuit on secondary side of control transformer.2. Wire two poles of control relay in series with contactor coil at line voltage.

    Mounting PositionDevices must be mounted to a sturdy vertical surface with the lineside terminals up. No other orientations are permitted.

    Operating TemperatureEquipment is designed for ambient temperature outside ofequipment enclosures to be -25° to 40°C. When contactor isenergized, temperatures will be above outside ambient inequipment enclosures. Temperature rises inside the enclosuresshould be limited so that internal air temperature does not exceed65° for sizes 00 to 6 and 60°C for sizes 7 to 9. If condensingmoisture is present, space heater kits should be used to preventcondensation when contactor is not energized.

    Storage temperature should be -30° to 65°C. If equipment isstored over 1 week, it may be necessary to cover the equipmentand provide a source of heat to prevent condensation.

    Control TransformersWhere to UseIt is often desirable to use a control transformer in conjunction witha magnetic starter or controller to provide low voltage control.

    Description—Factory WiredA transformer, with sufficient capacity for the control circuit,mounted with the starter can be supplied by the factory for themajority of transformer ratings and types of enclosures.

    Typical Size 1 Motor StarterGE's full voltage (600-Volt maximum) magnetic motor starter hasan encapsulated coil and a 3-leg overload relay to protect againstoverloads in all phases. It is on standard specifications of majormanufacturers. The line offers features and benefits most askedfor by users.Forms available include reversing and nonreversing, two-speed,and combination, sizes 00-9.• Toolless contactor disassembly (Sizes 00-4)—allows

    quick access for inspection and maintenance. Just release tworetainers and pull a clip to get at magnet, coil, and contacts.

    • Saddle clamp terminals (Sizes 00-1)—accommodate ring,spade, and stripped wire leads and carry permanent stamped-in identification. Staggered arrangement makes wiring easierand helps prevent shorting between phases.

    • Current-carrying components—contact tips are weld-resistant silver cadmium oxide (fine silver on sizes 00 and 0only). Contacts are installed in a wedge configuration forpositive make with minimum bounce.

    • Optional PF capacitor terminals—permit easy connectionof power factor correction capacitors between contactor andoverload relay for energy conservation.

    • Class 20 overload protection.• Visual trip indicator with manual reset—to avoid surprise

    restarts. Reset occurs on arm upstroke so a tripped conditioncan't be overridden by holding the arm down.

    • Manual weld check—provides a convenient test againstwelding of overload relay contacts. Just depress the weldcheck operator to trip the relay, run a simple continuity testacross the relay contacts, then depress the manual reset toreturn the starter to service.

    • Optional isolated NO contact on the overload relay-provides means of direct interface with programmable controlleror computer to monitor performance and diagnose faults.

    • Dual bimetals—anticipate overloads, responding to risingcurrent and temperature with faster tripping on severe overloadsfor better motor protection. Trip points are factory-calibratedfor accuracy.

    • ±10% trip adjustment—by turning a dial in the overload relayface allows "tuning" the protection to the motor on the spot.

  • GENEMA Rated Full Voltage Starter

    CR306, CR386 Nonreversing Magnetic Motor Starter,

    Typical CR306 Size 4magnetic motor starter

    ApplicationGE's magnetic motor starters listed here may be used for startingfull-voltage, nonreversing, single-speed ac motors up tp 1600horsepower, 600 Volts maximum, providing protection to themotor against running or stalled overloads.Their compact size and ease of wiring make them especiallysuitable for motor control centers, custom-type control panels,and switchgear equipment. Refer to page 1-4 for features of basicstarter.

    Ordering Directions1. Specify starter by complete Catalog Number.

    Example: CR306C103 is a Size 1 starter with 230-240-Volt,60-Hertz coil and in Type 1 general-purpose enclosure @$246.00, GO-10G.

    2. The final letter of the Catalog Number denotes extra auxiliarycontacts (sometimes referred to as auxiliary interlocks). Orderthe desired extra auxiliary contacts by replacing the final letterwith one from first column of auxiliary interlock table (see page1-58).Example: CR306C103AAB is Size 1 starter with one extranormally open, auxiliary contact @ $312.00, GO-10G.

    3. Starter forms are available with coils of other ratings than thoseshown on pages 1-6 to 1-7. Refer to coil suffix table, page 1-3for information. To order forms with other coil ratings, insertsuffix from coil table in place of fifth and sixth numbers oflisted starter Catalog Number shown on pages 1-6 to 1-7.Example: A CR306C102 NEMA Size 1, three-pole starter inType 1 enclosure with 24-Volt, 60-Hertz coil becomes aCR306C124 Catalog Number.

    4. For continuous rated motors with a service factor of 1 .15 to 1.25select the heater with maximum motor Amperes equal to orimmediately greater than the actual full-load current takendirectly from the nameplate of motor. Order heaters bycomplete Catalog Number from appropriate heater tables onpages 1-71 to 1-75. List Price $9.00 each, GO-10H. Packagedin quantities of three; must be ordered in multiples of three.
