Circuit breaker Icn=10000A / Icu=15kA 1P B 6A NBN106

The miniature circuit breaker marked as Icn=10000A / Icu=15kA 1P B 6A is an electrical device used to protect installations from the effects of overloads and short circuits. The type B tripping characteristic indicates a fast reaction to short-term loads and small short-circuit currents, which is particularly important when protecting circuits with connected devices sensitive to changes in current intensity.

The device has a single-pole design (total number of poles: 1), which means it takes up little space on the DIN rail - the width is only one module. This is an important feature for distribution systems where space is limited.

The rated voltage of this circuit breaker is 400 V AC, and its rated current is 6 A. This means it can operate in standard domestic and
