The F200 Ground Fault Equipment Protector (GFEP) protects equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit. The line consists of the two-pole F202 for single phase networks, and the four-pole F204 for split phases, Delta and Wye networks. Immediately detects ground faults by continuously measuring the current balance between live conductors and the neutral using a toroidal current transformer.
