The LineGard™ PGFM product family provides ELCI ground fault sensing and is designed & manufactured by North Shore Safety, a leader in innovative safety products. The PGFM series operates in tandem with an Airpax™ LEL series, UL 489 listed circuit breaker, with shunt trip & auxiliary switch manufactured by Sensata Technologies.

The combined assembly of the PGFM & Airpax™ breaker meets the requirements of ABYC E-11 for ground fault protection & main shore power circuit protection. The PGFM constantly monitors the current balance of the conductors (wires / cables) supplying power to the load. When a ground fault of 27mA nominal (30mA max) occurs, the PGFM uses the LEL’s shunt trip coil to signal the breaker trip.
