Overview
The ITI GFL080X116-2 ground fault sensor is a proven zero-sequence current transformer engineered for ground fault detection systems. This sensor is paired with ITI BGFL ground fault relays to monitor ac power systems and initiate protective trips when fault currents exceed pre-set thresholds. The GFL080X116-2 is rated for 30–360A trip current range and meets industry protection standards for electrical equipment.
Key Features
- Zero-sequence detection technology isolates ground faults from normal load currents
- Integral test winding enables combined sensor and relay testing without external injection equipment
- Rated for 50/60 Hz operation on single-phase ac systems
- 600 Volt insulation, 10 kV BIL (Basic Impulse Level) withstand capability
- Compact window-type design fits standard DIN or panel mounting configurations
- No. 8-32 brass terminal connections with lock washers for secure field termination
