Hard-wired GFCI for three-phase circuits
The Hubbell GFHW430 is a hard-wired ground-fault circuit interrupter rated for three-phase 120/208 V AC at 30 A. It provides personnel protection in industrial and commercial panels where a manual reset and panel or surface mounting are required. The Valox enclosure carries a 4X rating for harsh environments.
Thermal range and silent operation
Operating temperatures span from -30 °F to 150 °F, so the device remains functional in extreme cold and heat. No audible alert is fitted, which keeps electrical rooms quiet during normal operation. Power draw in the monitoring circuit is minimal and does not affect the protected load.
Sustained fault protection
Under a sustained ground-fault condition the unit trips and latches off until the manual reset is actuated, preventing automatic re-energisation of a faulty circuit. The 3/4 in NPT inlet accepts standard conduit for secure, permanent wiring. UL listing confirms compliance with the referenced safety standard for continuous duty.

Questions about this item
How is the 3/4 in NPT inlet used during installation, and what step is often missed?
The 3/4 in NPT inlet accepts conduit for hard-wired connection; the step often missed is applying thread sealant to maintain the 4X enclosure rating.
What maintenance will the Valox enclosure and manual reset mechanism need over time?
Inspect the Valox enclosure for cracks and test the manual reset button monthly to verify the GFCI still trips and resets correctly.
What is the first limit reached when the device runs continuously at 30 A in a 150 Degrees F ambient?
The 150 Degrees F maximum operating temperature is the first limit reached, causing the GFCI to trip and protect the circuit.
