R-MAG Magnetic Circuit Breaker
R-MAG® magnetically actuated dead tank outdoor vacuum circuit breaker
R-MAG outdoor breakers are designed with a maintenance-free, magnetically actuated mechanism to provide unparalleled reliability and safety in the field. The streamlined design enables easier integration and reduces training time for new users.
Benefits
- Compatible for overcurrent, reclosing and control functions
- Reduced maintenance with magnetic actuator and easy plug-and-play actuator circuitry
- Durable design exceeds ANSI C37.06 standard with a rating of 10,000 mechanical or load operations
Features
- Dead tank solution
- Designed and type tested based on latest ANSI standards
- 15/27/38 kV rating classes and up to 3,700 A continuous current
- Up to 40 kA short-circuit interrupting current
- Five-year full warranty
Reliability
- Minimized potential points of failure by having only one moving part in the magnetic actuator operating system
- Magnetic actuator is rated for 100,000 operations for the 15-27 kV R-MAGs and 50,000 operations for the 38 kV R-MAG
- ABB world-leading vacuum interrupters rated for 30,000 full load operations
- Tested for reliability in any environmental conditions from -50°C to +70°C
Easy Integration
- Back-up battery footprint reduced by 90%
- Only 8 seconds charging time from 1-100%; no pre-charge period is required, regardless of extended unutilized time in the yard
- Flexible solution for any type of relay, control, and test switches
- Up to 3 CTs, rated for both metering and/or protection, per bushing
Reduced Operation & Maintenance
- Shorter inspection times and longer maintenance intervals up to 10 years, as there are no coils or motors to replace and there is no gas or oil
- Reduced spare parts inventory
- Plug and play design of the ED2 electronic control board for rapid replacement in the field
