Code: P14035.
Electronic residual current protection relay with built-in 28 mm transformer, forming a single unit. Super-immunised type-A, with high-frequency current filtering and high immunity. True root mean square (TRMS) measurement.
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.
