The WRGU-10 MTT compact assembly forms a self-reclosing circuit breaker (overload and short-circuit) and earth leakage 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:
Earth leakage 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 earth leakage protection
Remote switch, for resets and external manual reclosures
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 earth leakage (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.
