HAGER CDA663D Residual Current Circuit Breaker 4P 63A 30mA Type A 10kA

Electrical installations require reliable protection against earth leakage currents to prevent electric shock and fire hazards. The HAGER CDA663D residual current circuit breaker (RCCB) detects residual currents up to 30 mA and disconnects the circuit instantly, safeguarding people and equipment in residential and commercial buildings.

Who is it for

Electricians and panel builders who need a robust, DIN-rail mountable RCCB for three-phase systems. It suits distribution boards in homes, offices, and industrial facilities where Type A protection is required for circuits with electronic loads.
