Introduction
The R-MAG® is truly the next generation in medium voltage vacuum circuit breaker technology. ABB is the first to combine the unique benefits of vacuum interrupter technology with a magnetic actuator designed to exploit these capabilities. Using a flux-shifting device with integral permanent magnets, the R-MAG mechanism has only one moving part. With simple open and close coils, an electronic controller and capacitors for energy storage, the R-MAG circuit breaker mechanism is capable of 10,000 load operations. These are a few of the features that mark a departure from the conventional spring-operated mechanism, introducing new capabilities and benefits for a smarter distribution system.
ABB makes safety our first priority by employing magnetic actu-ators to eliminate maintenance on coils, motors, and mechani-cally charged springs.
R-MAG benefits include: − Simple, less frequent maintenance
− Rated for 10,000 full load operations (five times ANSI requirements)
− No maintenance required on magnetic actuator − Plug & play actuator circuitry − Vacuum interrupters rated for 30,000 full load operations
− Increased reliability − Magnetic actuator has only one moving part − No spring charging motors to replace − No trip/close coils to replace − Less moving parts leads to less maintenance
R-MAG increased performance − 2,000 operations between servicing vs 500 operations bet-
ween servicing - ANSI C37.06 requirements − 10,000 mechanical or load operations vs 2,000 no-load me-
chanical operations - ANSI C37.06 requirements − No maintenance required on magnetic actuator − Eliminates open/close coils in stored spring mechanism lubri-
cation requirements
The R-MAG has three main components: − Vacuum interrupter assembly − Operating mechanism
− Provides reliable operation even after extended periods of inactivity
− Electronic control board − Compatible with all forms of overcurrent, reclosing and
control functions

Magnetic actuator
ABB has utilized magnetic actuators since 1997. One global team is dedicated to designing magnetic actuators for ABB products, including R-MAG breakers.
− 15 kV rated at 100,000 mechanical operations − 38 kV rated at 50,000 mechanical operations − One moving part − No maintenance required
Magnet life expectancyDevelopments in magnetic material technology allow the mag-netic actuator to be highly reliable over a long life time. Reduc-tion in magnetic flux density is less than 1% over 100 years at 248 °F (120 °C).

A magnetic actuator has one moving part and requires no maintenance.
A spring charged mechanism has over 300 total parts (many moving parts) and requires periodic maintenance.

Magnetic flux density distribution representation during a magnetic actuator opening operation
All operating mechanism functions are integrated in the mag-netic actuator of the R-MAG circuit breaker. The actuator is a bistable magnet system, in which armature change-of-state is accomplished by the magnetic field of two electrically excited coils. The armature is held magnetically in the limit positions by the fields of two rare-earth permanent magnets. Switching ope-rations are achieved by excitation of one of the two coils until the retaining force of the permanent magnets is exceeded.
Even after complete failure of the auxiliary power, the energy stored in the capacitors will allow electrical operation for 200 seconds. In the event of complete loss of control power, the circuit breaker can be tripped manually.
The armature of the magnetic actuator is linked to an operating shaft connected via insulated push rods to each of the vacuum interrupters.

Low power consumption electronic control board, with flexible voltage range and alarms, control the R-MAG magnetic actuator.
Advantages of electronic controls − Flexibility of control voltages − Consistency of operation utilizing capacitor energy − Built-in trip & close coil features − Built-in breaker status indication − Coil protection − Ready and Not-Ready alarm
Flexibility of control voltages − Two control boards cover all control power requirements:
− Low voltage: 17 - 75 VDC or 21 - 52 VAC − High voltage: 77 - 280 VDC or 85 - 264 VAC
− Control board is independent of AC or DC − 1 control board covers 120 VAC, 125 VDC, 240 VAC
application − Ability to test a 125 VDC breaker with 120 VAC
− Low power requirements - 93 watt normal (41 watt power optional)
− Less than 1A at 125 VDC during capacitor charging (7 seconds)
− Plug & play removal & installation of control board assembly − Easy board conversion between low and high control
power requirements − Eliminates changing of trip and close coils, motors − Increased safety
− Wide range of input voltages − Minimizes damage from voltage spikes or higher charging
voltages
Consistency of operation utilizing capacitor energy − Smaller battery system - can be minimal since there is no
high instantaneous load on charging, closing or tripping − Voltage drop is not an issue when running control power
from battery system (smaller wiring can be used) − Operate multiple breakers simultaneously
− Sufficient energy to operate multiple breakers from station batteries simultaneously
− Constant energy source − Energy for closing and tripping is constant (regardless of
station battery voltage) thus closing and opening speed are consistent
Using capacitors for stored energy − The 0.1 Farad Electrolytic capacitors are designed to be ope-
rated in the temperature range of -40 °F to 185 °F (-40 °C to 85 °C)
− Extreme temperature option also available: -67 °F to 221 °F (-55 °C to 105 °C)
− Recommended capacitor replacement − 20 years for an average yearly temperature (in the outdoor
breaker enclosure) of less than 122 °F (50 °C) − 15 years for tropical climates
Built in breaker status indicationUnit-Ready and Not-Ready output contacts will provide an alarm under the following conditions:
− Drop off auxiliary supply voltage − Low voltage on capacitor
Capacitor vs number of operations − Open-close-open: 78 V − Close-open: 72.5 V − Cannot close breaker without sufficient energy to trip − Open: 49 V
