Protection and Control
WGC-55
Residual current transformer
Code: P10153
Overview
This new range features a series of improvements intended in particular for installing units on switchboards. Along with the usual attachment elements, this unit can be installed on DIN rails using an accessory, which facilitates its installation.
The residual current transformers of the WGC series offer better immunity to the transient current spikes that usually trigger the residual current protection. The residual current transformers of the WGC series have been designed to operate with the relays of the WGC series. The sensitivity (trip current) of the transformer-relay assembly is established by the associated relay.
