Circuit breaker Icn=10000A / Icu=15kA 3P B 10A NBN310

A miniature circuit breaker with B tripping characteristic and a rated current of 10A is an electrical device that plays a key role in ensuring the safety of electrical installations. Its main task is to protect conductors from the effects of overloads and short circuits, which is of significant importance for fire prevention and the protection of equipment connected to the network.

The Type B tripping characteristic determines the speed of the breaker's reaction to the occurrence of excessive current. Circuit breakers of this type are particularly recommended for use in domestic circuits or where devices generating small transient inrush currents are connected, such as lighting or general-purpose sockets.
