Datasheet
Datasheet Summary
Powered by GS/AI

The SE-330 is a neutral-grounding-resistor monitoring relay that detects open or shorted grounding resistors and ground faults as low as 100 mA using DFT filtering to reject harmonic noise. It provides two programmable Form C and one Form A output contacts, an analog 4-20 mA output, and a pulsed contactor output for fault location. The relay includes an on-board microSD card for data logging, a 100-event trip recorder, and is conformally coated. It supports DeviceNet, IEC 61850, Modbus TCP, and Ethernet/IP communications, and meets CSA, UL, CE, and RCM certifications. Dimensions are 213 mm H × 98 mm W × 132 mm D, with panel or surface mounting. The SE-330-25-00 variant has a 48 Vdc supply and EtherNet (Dual SC Fiber) communications.
