The SE-107 is a ground-fault ground-check monitor for resistance-grounded systems, designed to protect portable equipment in underground mining applications with trailing cables up to 5 kV. It operates in UV-trip mode only, with a fail-safe ground-check circuit and standard harmonic filtering to prevent false operation. The device has adjustable trip levels of 0.5, 2.0, and 4.0 A and trip time settings from 0.1 to 1.0 s. It includes a 1N5339B termination device and requires a CT200 series current transformer. The SE-107 is conformally coated for harsh environments and features a local and remote reset button. Dimensions are 150 mm high, 109 mm wide, and 100 mm deep. It is CSA certified, UL Listed (E340889), and C-Tick certified. Input voltage is 120 Vac or 120 Vac/Vdc, as specified in the ordering information.
The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-105/SE-107 is an excellent choice for trailing cables 5 kV and under in underground mining applications. For higher voltages or long-cable applications, see the SE-134C/SE-135.
