INFORMATION

Description

Self-reclosing electronic relay of motorized circuit breakers. The relays of the RRM series can be used to control, send remote signals and for the remote control of the associated motorized circuit breaker (MT series).

The RRM relay has the following functions:

  • Motorized circuit breaker control:
  • Automatic reclosing
  • Remote connection/disconnection (non-reclosing)

Signalling:

  • Local, with LED
  • Remote signalling with relay of the reclosing lock (in RRM-P)
  • RS-485 Communications (in RRM-C)
Remote control of the automatic switch

The complete reclosing group is composed of the following elements:

  • Motorized circuit breaker of the MT series (2 or 4 poles)
  • Control relay RRM.

Applications

The RRM relays can be used in all applications that require a self-reclosing motorized circuit breaker after a trigger or with the use of remote control systems. It has been specially designed to work with the circuit breakers of the MT series.
