ETL3-40M Residual Current Circuit Breakers with Overcurrent Protection (RCBO) provide combined protection against overload, short-circuit and earth leakage faults. Designed for 400/415 V (3P+N) power systems with rated currents up to 40A, they are suitable for both residential and industrial installations.
The range offers breaking capacities of 6 kA and 10 kA and is equipped with a reliable electromagnetic trip unit for fast fault clearance.
