As a complement to the basic version of our HPL circuit breakers, which are primarily designed for conventional substation solutions, there is a disconnecting circuit breaker configuration with the disconnecting function integrated in the breaking chamber.
The HPL Disconnecting Circuit Breaker (DCB) is based on the HPL standard circuit breaker. The disconnecting function is integrated in the breaking chamber. That means that the circuit breaker fulfills all requirements for a circuit breaker as well as all requirements for a disconnector. A safe interlocking system, composite insulators and a motordriven grounding switch provide personal safety.
With our Disconnecting Circuit Breaker as a base, we now offer an alternative that provide opportunities to both simplify substations and save space.
