The OD3Mag™ is the first MV Substation Breaker that allows the choice of 1-phase or 3-phase operation.
This feature allows you the performance and ratings of a circuit breaker and the functionality of a recloser. By tripping individual phases in distribution systems, utilities are able to improve their SAIDI and SAIFI scores and enhance the resiliency of their network.
