Ground Fault Sensors
Category Selection
Ground fault sensors and residual current monitors are essential devices that help prevent electric shock and fire by detecting current imbalances caused by leakage to ground.
Standard ground fault sensors provide basic protection with low trip thresholds, below the fatal level, to safeguard people from electric shock. They detect sinusoidal AC faults and typically activate shunt trips to quickly de-energize a circuit when a fault occurs.
Residual current monitors offer more advanced and versatile protection. Type B earthing models detect several fault types, including AC, pulsating DC, and smooth DC, making them essential for applications where standard sensors would be unable to detect faults or might be blinded by DC leakage. Their wide, adjustable trip ranges support system-level functions such as selective coordination and backup protection against larger faults.

AC Ground Fault Sensors
Newest Additions!
- More GFSL series large aperture ground fault sensors
Ground fault sensors detect leakage currents at low trip levels in grounded AC systems to protect people, equipment, and processes from damage caused by ground faults. Jumper-selectable setpoints help reduce nuisance tripping while ensuring effective protection for sensitive machine electronics.
AC/DC Residual Current Monitors
New!
Residual current monitors protect equipment, facilities, and processes by detecting leakage currents in grounded AC or DC systems. They provide warning and alarm outputs with wide adjustment ranges to support preventive maintenance and tailored fault responses while avoiding unnecessary trips.
