Ground Fault Sensors

Ground-fault relays detect leakage current and change their output contacts when a selected trip point is reached. Ground-fault transducers provide a proportional analog signal for a controller, meter or data logger. Compare AC or DC input, output type, trip range, supply and maximum wire-bundle diameter to select a suitable sensor for your application.

Wire-bundle filters show the maximum supported bundle diameter stated for each family. Check the product specifications and installation instructions for the complete assembly and conductor arrangement.
