Carlo Gavazzi Monitoring Relay Earth Leakage Din-Rail DEB71DM24A30

Carlo Gavazzi Monitoring Relay 1-Phase or 3-Phase Earth Leakage Adjustable 300mA to 30A, DIN-Rail, 2x SPDT, 50-60Hz, Supply: 24-240VAC.

The DEB71 is an adjustable modular residual current relay which, in conjunction with the MCB and the CT, provides the protection of people against electrocution, or protection of properties against fire, 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 setpoint value providing a warning to user, the other output is used to shut down the system to prevent accidents. The DEB is a flexible device and can be used for all the applications where the loss of insulation, and/or grounding failure, of the loads or lines may cause injuries to people due to electrocution or ignite fires.

General Characteristics

• 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.
• Earthed / unearthed mains. The DEB can be used on both three phase or single phase, which not necessarily need to be earthed.
