Eaton GFSX1 Ground Fault Interrupter - IP66 Hazardous
Part Number: GFSX1
Quick Summary
Ground Fault Interrupter GFSX1 protects circuits in hazardous locations by interrupting faults quickly. In harsh environments, conventional devices can corrode, trip unpredictably, or require frequent maintenance, leading to downtime and safety risks. This unit offers IP66 and NEMA 4X protection, paired with NEC/CEC hazardous location ratings such as Class I Division 2, Zone 2, to ensure compliance and reliability. Its factory-sealed copper-free aluminum housing and 125 VAC operation deliver long-term performance in rugged plants, while a precise 5 mA trip and 20 A rating support safe, uninterrupted production. For engineers and procurement teams, GFSX1 combines robust protection with installation simplicity, enabling safer upgrades without reworking plant infrastructure and reducing lifecycle costs.
