LTB Combined
Disconnecting Circuit Breaker

As a complement to the basic version of our LTB 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 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.

With DCB we have created the capability to design substations without conventional disconnectors, which improves operational availability.
