GFP243-1200

GROUND FAULT CURRENT DETECTION

With Inverse Time Capability

Model GFP Relay

The GFP system is designed for electrical equipment protection, not for personnel protection

Application: 

These Class 1 (Model GFP) Ground Fault relays and sensors are used together to provide a system for detecting ground fault current in a grounded AC power system. When the system detects a ground fault that reaches a pre-selected current level and time delay, the relay initiates a trip signal for a shunt trip disconnect device to open and clear the fault.
The relays are also available with interlocks (for coordination of multiple devices in a system) and without interlocks (for single device systems).
The GFP non-interlock relays form/fit/function replacements for the BGFL Ground Fault relay without interlock.
