The DEA71 is a modular residual current relay which, in conjunction with the MCB and the CT, provides protection against possible risks arising from insulation or grounding faults, by interrupting the mains on faulty loads or lines.

The setpoint of the leakage current is factory set to 30mA or 300mA according to model and it is not adjustable.

The device is equipped with two changeover relay outputs.

One output triggers at 60% of fault current setpoint value providing a warning to user, the other output is used to shut down the system to prevent accidents.

Benefits

• Fixed trip level, easy setup “Plug’n Play”. Time saving installation, reliable tripping level and safety against tampering.

• 2 outputs. Two relay outputs provide, besides the alarm signal an additional warning output.

• Nuisance tripping safe. EN 60947-2 Annex M conformity.

• Remote R/T button. Input for external reset switch allows remote system restart in case of tripping.

• Single / Threephase mains. The DEA71 can be used on both three phase or single phase.
