Disconnecting Circuit Breakers

The disconnecting function is included in the circuit breaker and no separate disconnectors are necessary. It is now possible to build substations with minimized need for maintenance and space, low failure rate, increased safety and low Life Cycle Cost.

Our offering

  • DCB-HPL B

    HPL circuit breakers with integrated disconnecting function. Built on grounding switch for voltages up to 550 kV

  • DCB-LTB D

    LTB circuit breakers with integrated disconnecting function. Built on grounding switch for voltages up to 145 kV.

Applications

  • DCB with FOCS

    DCB with FOCS

    Use the light to measure the current. FOCS is a Fibre Optic Current Sensor that replaces the conventional current transformer for current measurement. A smart grid ready solution for use with IEC 61850-9-2LE standard digital outputs.
