Ground Fault Equipment Protector
The ABB (New Berlin, WI) Low Voltage Products division has introduced the F200 Ground Fault Equipment Protector (GFEP), designed to protect equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit. A ground fault is caused by an insulation loss between a live conductor and an exposed conductive part that creates a flow of current to the ground. Most short circuits initially manifest as ground faults, which if undetected, can cause serious and costly damage to electrical systems and equipment. An ABB F200 GFEP added to an electrical system trips when the system leaks a significant current to ground, preventing the potential short circuit before such damage can occur.
