When used in conjunction with a CTG series core balance current transformer and appropriate circuit breaker, DEA71 and DEB71 earth-leaking monitoring relays provide machine protection against fault currents and help to reduce fire hazards. These earth leakage relays react to small changes in current that can occur because of wire insulation breakdown or grounding failure. The two models, each offering choices of threshold ranges, allow users to find the right solution for their unique requirements. DEA71 features fixed trip levels and safety against tampering. DEB71 provides adjustable trip levels and includes an adjustable time delay; a lockable front cover provides further tamper protection.
