What Are Circuit Breakers and Disconnects? Circuit breakers open a circuit in case of current overload for safety, and unlike fuses, they can be manually reset by an operator or computer. Disconnects manually or remotely open a circuit for branch isolation or to allow maintenance, but do not monitor the flow of current or open automatically.

The smart choice for maximum availability at a low total cost. A Disconnecting Circuit Breaker (DCB) provides the functionality of a circuit breaker and a disconnector combined in a single unit. Without the need for separate disconnectors, up to 75 percent less space is required.
Circuit Breaker is a protection device (such as MCB, ACB, SF6, OCB etc) which disconnects the circuit in case of overload and short circuit faults. Disconnector and Isolator switches provide isolating function i.e. disconnecting the supply from all or a portion of installation e.g. in power plants. Types.

Circuit breaker disconnects are essential safety devices that protect electrical circuits from overload and short circuits. They are typically located in the main electrical panel of a building, and they can be used to isolate individual circuits or groups of circuits for maintenance or repair.
The DCB (Disconnecting Circuit Breaker) is used as a circuit breaker and also as a disconnector – two functions combined in one device. An additional air-insulated earthing switch can be mounted onto the supporting structure for voltages up to 145 kV. Ask our experts. Main features: Combination of circuit breaker and disconnector in one device.
