Toroidal Transformer Wgc-35 Diameter 35Mm

WGC-35 toroidal transformer, diameter 35mm. In this new range, a series of improvements are presented, especially thinking about the installation of equipment in distribution boards. In addition to the usual fixings for installation, the possibility of doing so on a DIN rail using an accessory is added, making installation easier. The WGC series differential transformer has better immunity against transient current spikes that usually cause differential protection trips. The WGC series differential transformer are designed to work with the WGC series relays. The sensitivity (trigger current) of the transformer-relay assembly is set by the associated relay.
