The SE-134C-XGC-00 is a microprocessor-based ground-fault and ground-check monitor for resistance-grounded or solidly grounded systems, protecting portable equipment by monitoring ground conductor integrity. It features a 45 Ω GC trip resistance and XGC option enabling 10 km maximum cable length for ground-check monitoring. The unit operates on 65-265 V ac or 85-275 V dc, with trip levels from 0.5 to 12.5 A and time delays from 0.1 to 2.5 s. It includes harmonics filtering, a test button, and isolated Form A, Form B, and two Form C output contacts. Panel or surface mounting is supported. Conformal coating and fail-safe circuitry are standard. The unit requires an SE-CS10 current transformer and SE-TA6A termination assembly. It is CSA certified and UL listed (E340889).
