Circuit breaker Icn=10000A / Icu=15kA 3P B 20A NBN320

An MCB with B tripping characteristic and a rated current of 20 A is an essential element in every electrical installation, ensuring network safety and protecting devices from the effects of overloads or short circuits. Its breaking capacity Icn of up to 10000A and Icu equal to 15kA testify to high resistance to extreme operating conditions, which guarantees reliable protection even during very large short-circuit currents.

The three-pole design of this MCB allows for the simultaneous control of three phases, which is the standard for three-phase installations. This makes it possible to quickly isolate a damaged circuit from the rest of the system, minimizing the risk of further damage or fire.

The rated voltage of the device is 400 V AC, making it suitable for use in
