earth-leakage protection relay / 2 NO/NC / differential / IEC
differential, IEC, panel-mount, DIN rail
24 V, 48 V, 110 V, 240 V
The ELR-7 is a device that protects the earth leakage. The device is constructed in a flush mounting enclosure of 48mm x 48mm with 72mm depth. The dimension reduces to a minimum due to its size, applicable to applications wherein space is critical.
The device becomes immune to external distortions due to its built-in filter placed at the input circuits. It has a tripping current of 25mA ÷ 25 A and a tripping delay of 0,02 ÷ 5 seconds. The device is equipped with a micro switch. This switch chooses the working mode of the end relay, whether it is normally de-energized or normally energized.
