What is a differential circuit breaker?

A differential circuit breaker combines the functions of two separate devices: a circuit breaker and an RCD (residual current device). The device is designed to protect against electric shock during human contact with the surface of the equipment or its parts that conduct current.

How to choose a circuit breaker?

The circuit breaker is selected based on the values of the total leakage current and the rated current. The best electric machines are those in which the maximum switching capacity for devices in the group is 6 kA. The same indicator for terminal devices should be at least 3 kA.
