The SE-502-01 is a ground-fault and ground-continuity detector designed for personnel protection in 120/208 V systems, offering Class-A GFCI trip levels with a 5 mA detection threshold and a maximum ground-fault current limit of 100 mA. It features two Form C output contacts for alarm or tripping, continuous neutral continuity monitoring, and ground-proving capability. The device operates on 120 Vac, 50/60 Hz, and is mounted via DIN or surface mounting. Its dimensions are 75 mm high, 100 mm wide, and 113 mm deep. It includes a reset button and a remote reset input, and meets IEEE device numbers 64, 86, and 95. The unit carries a five-year warranty.
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.
