$4,923$5,907 (-17%)
Littelfuse SE-330-06-01 neutral grounding resistor (NGR) monitor — universal 65–265 VAC / 85–275 VDC supply, IEC 61850-ready, analog 4–20 mA. Genuine Littelfuse unit with fast delivery from Batam across Indonesia & Southeast Asia.
Littelfuse SE-330-06-01 is a neutral grounding resistor (NGR) monitor engineered for resistance-grounded AC systems. With a universal 65–265 VAC / 85–275 VDC supply, analog 4–20 mA output and IEC 61850-capable communications, it delivers continuous NGR and ground-fault protection for substations, generators, industrial plants and process-control systems as an NGR monitor / protection relay. Features include dual RJ45 ports, pulsing output and adjustable pickup and delay for coordination.
Key Features
- Continuous NGR and ground-fault monitoring with fast detection of resistor failures
- Adjustable sensitivity 2–100 % in 1 % increments for precise pickup
- Programmable relay outputs and selectable operating modes for system coordination
- Analog 4–20 mA output plus pulsing output for auxiliary monitoring
- Dual RJ45 ports and IEC 61850 support for substation-grade communications
- Conformal-coated electronics and universal CT compatibility for harsh environments
