The DEB71 is an adjustable 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 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

• Adjustable trip level. Adjustable leakage threshold from 30mA to 5A or from 300mA to 30A.

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

• Level indication. LED Bar shows at a glance the real time leakage level.

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

• Anti tampering. Sealable front lid provides protection against possible tampering.

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

• Single / Threephase mains. The DEB71 can be used on both three phase or single phase.
