Smart earth leakage protection Earth leakage transformers Description 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 earth leakage transformers of the WGC series offer better immunity to the transient current spikes that usually trigger the earth leakage protection. The earth leakage 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. Technical features Electrical insulation Direct thermal current Thermal short-circuit current, Ith Dynamic current, Idyn Optoisolated voltage-free Terminal protection Screw-in fasteners DIN rail (with accessory) Housing material / colour Self-extinguishing class Product standards Connection Assigned transformation ratio, Kn Measurement accuracy Mechanical features Assigned impulse voltage / pollution Operating conditions Maximum assigned service voltage Measurement circuit Two wire (S1-S2) connection type Screw-in terminal (pzl screw) Dimensions of rigid/flexible conductors 0.1...2.5 mm2 / 27...12 AWG Connection to protection and measurement devices (RCD, RCM) Cabling with wire section ≥ 1 mm2 Cabling with braided and shielded wire section ≥ 1 mm2 Accessory for assembly on DIN rail (for WGC-20SC, WGC-25, WGC-30-SC, WGC-35 & WGC-55) * Built-in accessory for assembly on D
