Earth Leakage Relays WRU10

Electronic differential protection relay with built-in 28 mm transformer, constituting one unit.

Type A high-insulation, with high-frequency current filter and high insulation. Monitoring using true root mean square.

Display with LEDs and display:

Units with three programmable output contact relays, one switched and two simple. The main relay is for the protection provided by the contact or trigger relay of the automatic switch while the two others are for the pre-alarm.

It also has a voltage input for external triggering and re-arming.

Application:

WRU-10 relays enable smart differential protection. Their design features guarantee maximum security and electrical service continuity, avoiding unwanted tripping.

Viewing the instantaneous leakage value on the display, together with the prealarm indicators, makes it possible to obtain information on the status of lines to be protected, and to perform adequate preventive maintenance.
