Applications

Ideal for protection of human life and equipment in electrical distribution systems, particularly in four-pole settings where the neutral must be switched as part of the residual current monitoring. Commonly used in residential installations, commercial switchboards, and light industrial control panels where earth-leakage protection at 30 mA and 25 A rated current is required.
