Eaton Y7-170431 FRCMM-25/2/003-A Residual Current Circuit Breaker, 2-Pole, 25 A, 30 mA, Type A

Electrical faults can cause dangerous leakage currents that standard circuit breakers do not detect, putting people and equipment at risk. The Eaton Y7-170431 FRCMM-25/2/003-A residual current circuit breaker (RCCB) provides essential protection by instantly disconnecting the circuit when a residual current of 30 mA or more is detected.

Who is it for

This RCCB is intended for electricians and panel builders installing protection in residential, commercial, and light industrial electrical distribution boards. It is suitable for circuits where protection against both AC and pulsating DC residual currents is required.

Main features

• 2-pole design for single-phase 230 V AC circuits
