This is a non-automatic DC disconnect, not an overcurrent circuit breaker. C/D jumper arrangement, rear busbar orientation, supply direction and the 2500A dimensions must match the final assembly. Select upstream protection separately.
Typical applications
- High-current isolation for photovoltaic and energy-storage DC circuits.
- Fixed switchboard assemblies requiring a documented 1500Vdc disconnection and coordinated upstream protection.
