Single-pole circuit breakers (1P)

 prices on 16 models

1 pole

— the simplest type of protective device for single-phase networks. It has one screw terminal at the input and one at the output. Such devices are used, in particular, to protect socket circuits and lighting circuits running from the distribution board to an apartment, separately. The clear advantages of single-pole models include their compactness. In addition, circuit breakers for individual network segments can be installed virtually any distance apart, and their characteristics may also differ (for example, the trip current of a circuit breaker for sockets should be higher than that for lighting).
