What is Circuit Breaker Conversion ?
- It brings a Low Voltage Power Air Circuit Breaker to current standards of overcurrent and ground fault protection
- This is accomplished with the replacement of the old direct operating electromechanical overloads with new current sensors, a self powered solid-state electronic trip unit, tripping actuator and all copper connectors and their mounting parts.
- At the same time, maintenance is performed on the breaker to bring it to manufacturer's specifications
Why Convert ?
- Older type Air Circuit Breakers fitted with the original series electro-mechanical trip units do not always function reliably
- Tripping characteristics become non-repeatable
- Coordination becomes difficult or impossible
- Cost-effective alternative to buying a new breaker
- Electronic Protection provides more functions and provides a vehicle for communications/monitoring
- Equipment and personnel safety
Conversions using either Carriere or Federal Pioneer electronic relays are available.
