The GFHW13005 is a hard-wired ground fault circuit interrupter designed for industrial and commercial power protection applications. It operates at 30A 120V AC with a 4–6 mA trip level and features an electromagnetic latching mechanism for reliable fault detection. The device provides open neutral protection and trips upon loss of neutral, with a red blinking light indicator and optional audible alarm to signal fault conditions. It is manually reset and trips when ground and neutral touch at the load side, making it suitable for protecting personnel and equipment in industrial environments where ground faults pose a safety risk.
