ARMAT Residual Current Circuit Breaker B10N 1P+N B50 100mA type A (36mm) IEK AR-B10N-1N-B050A100

ARMAT B10N series residual current circuit breakers (RCCB) with 1P+N pole topology are a reliable solution for industrial, power engineering, and domestic applications. A rated breaking capacity of 10 kA guarantees reliable operation of the device even at high short-circuit currents. The B10N 1P+N pole topology means that the protection functions against overload and short-circuit currents, as well as the arc-extinguishing ferromagnetic grid, are implemented in the phase pole. An independent free-trip mechanism with instantaneous switching ensures safe connection, and the terminal protective shutter prevents incorrect connection and errors during conductor installation. PIN and FORK busbar connection is implemented at the top and bottom of the device. B10N 1P+N allows for the connection of any additional ARMAT AUX series modular devices (additional contacts and trip units), as well as an RHN type rotary handle, an HLC type handle locking, and an OTL type sealing plug. The product range includes devices with rated currents from 6 A to 63 A, with B and C overcurrent trip characteristics, type A differential current protection characteristic, with rated differential trip currents of 30, 100, 300 mA.
