Releu de defect la pământ multicanal – X52UB6 (tip B)

X52UB6 is a multichannel Earth Leakage Relay of Type B.

The Multichannel earth leakage relays COMBI 6 have been designed for the monitoring and protection of up to 6 independent systems. A single instrument of 3 DIN modules size allows a considerable optimization of the overall dimensions and of the wiring connection procedures.



Main functions

  • Monitoring and protection of up to 6 independent residual current circuits in a single device.
  • Compact 3-module DIN housing allowing space-saving in distribution boards.
  • Programming via 4 front buttons, with copy/paste function for settings between channels.
  • Wide range of trip current and delay settings – divided into 3 ranges for greater precision.
  • Continuous monitoring of the presence and correctness of the connection with residual current transformers.
  • Selectable reset mode: manual or automatic.
  • Input for remote reset and optional alarm output and RS485 Modbus RTU interface.
  • Optional real-time clock (RTC).
