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.
- Operating Range: Trip currents models are available for 5-60, 30-360, and 100-1200A. The time delay is adjustable from instantaneous to 1 second.
