CARLO GAVAZZI DEA71DM24A030 Earth Leakage Monitoring Relay
The Carlo Gavazzi DEA71DM24A030 is a modular residual current relay that provides protection against risks arising from insulation or grounding faults by interrupting the mains on faulty loads or lines. It incorporates a fixed leakage current setpoint (300mA) and two changeover relay outputs – one for alarm and one for system shutdown. This relay is particularly well-suited for building automation systems in household and commercial buildings, offering reliable protection and safety against tampering. Its features include a nuisance tripping safe design, remote reset functionality, and compatibility with both single and three-phase mains.
