Item NO.:
ZG955current transformer for GFCI manufacturer ZG955
The GFCI component must consist of ZCT and GNT coils. The ZCT coil is used to detect a small ground fault difference current between the live line and the earth line .The GNT coil is used to detect an over-current caused by arcing or short circuit of the cable fire or excessive current change. Current transformer is mainly used in GFCI sockets or plugs used in near-water environments such as kitchens, bathrooms, car washes, and arc fault breaker sockets or plugs for air conditioners.

GFCI Current Transformer Application:
√ Sensing toroid using to sense minimal differential current caused by the ground fault
√ Grounded neutral toroid using to sense unexpected excessive current change or overload current caused by the arc resulted from the fire or the short circuit
√ GFCI current transformer series are mainly applied to GFCI plugs, GFCI receptacles,connecting with various electric equipments, such as EV charger,Air-conditioner,Washing machine,Water heater, Car-washing equipment etc
√ Currently,our GFCI CTs are widely used for floor heating and HVAC controls.
√ And also these assemblies are applied to the AFCI used in the air-condition
