Available with either solid-state or mechanical outputs, AG and AGL ground fault sensors measure all current carrying conductors in grounded single- and 3-phase delta or wye systems. The solid-state models provides unlimited switch operating life, superior resistance to shock and vibration, high switch speeds, and high input-output isolation, according to the company. Mechanical outputs are available in solid-core enclosures with a choice between normally open (NO) normally closed (NC) SPST latching relay and an SPDT Form C relay with auto-reset. These models can be ordered with either factory-adjusted or field-adjustable setpoints, or a “Tri-set” option with three factory-adjusted set points. Optional EMI/RFI coating is available.
