INFORMATION

Description

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.

  • Display with LEDs and display:
    • Residual current protection parameters.
    • Protection trip current.
    • Protection status messages, etc.
  • Unit with three programmable contact output relays, one switched and two single. The main relay is for the protection associated with the contact or trigger relay of the circuit breaker while the two others are for the prealarm.
  • It also has a voltage-free input for external tripping and rearming.
  • Assembly on DIN 46277 rail (EN 50022), 3 modules.
  • Connection by pluggable terminal strips.

Applications

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.
