Earth-leakage protection relay WRU10K series

DIN railprogrammabledigital

Electronic residual current protection relay for self-reclosing, with Ø28 mm built-in toroidal transformer, forming a single unit. Type A relay (IEC 60755) ultra-immunized. True root mean square measure (TRMS). Display with LED and backlit (LCD) display: Residual current protection / reclosing parameters. Protection trip current Number of reclosures Protection status messages, etc. Device with three output relays, one for indicating locking status and the other two for the trip and subsequent reset of the circuit breaker (MCB-P). It is only used with the MCB-P, with it not being possible to associate it with others. It has voltage-free input for remote control trip/reset operations. The WRU-10K relays connected to the MCB-P guarantee self-reclosing residual current and circuit breaker protection after an residual current trip. It is a good solution for those infrastructures that are hard to control and monitor because of their location. Control boards for: Telephony systems DTT systems Computer systems, UPS
