DEA71 Earth Leakage Monitoring Relay Benefits Fixed trip level, easy setupPlug n Pla. 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. Description 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. Applications Having the fixed setting the DEA71 is particularly indicated in building automation for the installation in household or commercial buildings for properties protection. 25/07/2018 DEA71 DS ENG Carlo Gavazzi Controls S.p.A. 1DEA71 Structure A H B C D E F G I J Element Component Function A Output 1 Main alarm SPDT relay output: 11 C, 12 NC, 14 NO B LED ON Power ON GREEN LED C Test pushbutton When pressed it will test the system integrity D LED AL Alarm RED LED, it turns ON when current exceeds 80% of In E Reset pushbutton Restores operation after an alarm has been triggered F LED PRE Warning YELLOW LED.
