The SE-502 Ground-Fault Ground-Continuity Detector provides Class-A GFCI trip level and trip times for personnel protection. As little as 5 mA of ground-fault current can be detected, and the internal neutral-grounding resistor limits the maximum ground-fault current to 100 mA. The SE-502 can be used on both energized and de-energized systems, and will continuously monitor neutral continuity, detect a load-side grounded neutral, and is capable of ground proving. These features make the SE-502 ideal for use with 120/208 V portable generators and in heat-trace applications.
The SE-502 Ground-Fault Ground-Continuity Detector will be discontinued after component inventory is depleted. Once inventory is depleted, there is no plan for offering a direct-replacement product. Please contact your Littelfuse representative to discuss alternative solutions.
