elec2-d EARTH LEAKAGE & EARTH CONTINUITY RELAY

PRODUCT OVERVIEW

The elec2-d relay provides high-integrity earth leakage (EL) and earth continuity (EC) protection for mining and industrial  power systems. Designed and engineered in Australia, it delivers precise, reliable performance for VVVF drives and fixed speed circuits while meeting key AS/NZS and IEC standards.

The elec2-d is a din rail mounted relay.
