ABB LTB Disconnecting Circuit Breakers

share

The LTB Disconnecting Circuit Breaker (DCB) is based on the LTB 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.
