Ground Fault Sensors-Fixed

Ground Fault Sensors help protect people, products, and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded systems.  Using the “Zero Sum” Operating Principle, as soon as current leaks to ground (fault condition) the two currents become imbalanced and a net magnetic field results. These sensors monitor this field and trip alarm contacts when the leakage rises above a set point.
 
Ground fault sensors are used in a variety of applications, including personal protection and equipment protection. They come in a variety of sizes and styles to meet a range of needs.
 
Ground Fault Sensors Applications

• Personal protection:
• Equipment Protection
• Eliminate nuisance tripping
• Meets requirements as stipulated by governmental and industrial regulatory groups for ground fault sensing
• Replace bulky two-piece sensor solutions that require separate CTs or relay modules
• Use with shunt trip breakers to provide total ground fault protection to sensitive machine electronics.
• Detect ground faults in resistance/impedance heating, industrial automation and control, theatrical lighting, portable power distribution, and snow melt/heat trace applications
• Sense progressive levels of ground fault in motors or heating systems to detect deterioration prior to catastrophic failure.

Key Features of Ground Fault Sensors to Consider

• N.O./N.C. solid-state switch or mechanical relay outputs
• Normally energized or normally de-energized contacts
• Noise Immunity option for use in EMI/RFI sensitive environments
• Applicable on single- and three-phase systems
• Ideal for use with shunt trip breakers
• Magnetically isolated from monitored circuit and control power.
• UL, CE approved
• Finger-safe Terminals for Worry-free Installation and Operation
• Uses “Zero Sum” Operating Principle to reliably sense imbalance in magnetic fields associated with current leakage to ground
