INFORMATION

Description

The WRGU-10 MTT compact assembly forms a self-reclosing circuit breaker (overload and short-circuit) and residual current protection system in single-phase or threephase electrical installations with a neutral of up to 63 A. The assembly is composed of the following elements:

  • Residual current relay for protection, with RGU-10 MTT self-reclosing function
  • MP-T series motorized circuit breaker as an overload and short-circuit protection element, and as a circuit breaker in residual current protection
  • WGC residual current transformer, residual current sensor for residual current protection
  • Remote switch, for resets and external manual reclosures

Applications

The WRGU-10 MTT groups can be used to make safety compatible with the continuity of the service in remote installations or installations with more complicated maintenance. They ensure residual current (mandatory) and circuit breaker protection, guaranteeing selfreclosing for either of the two reasons. It is a very good solution in installations in special locations that are hard to control and monitor: telephony installations, television repeaters, refrigerating chambers, etc.

  • Telephony systems
  • DTT systems
  • Industrial refrigerating chambers
