DETAILED DESCRIPTION

DEΒ71DM..

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
