$4,971$5,965 (-17%)
Littelfuse SE-330HV-06-00 neutral grounding resistor (NGR) monitor, 65–265 V AC / 85–275 V DC supply, with IEC 61850 Ethernet and dual RJ45. Genuine Littelfuse unit from Batam — fast delivery across Indonesia & Southeast Asia.
The Littelfuse SE-330HV-06-00 is a neutral grounding resistor (NGR) monitor designed for resistance-grounded AC systems. This NGR monitor (SE-330 series) accepts 65–265 V AC or 85–275 V DC supply and provides continuous ground-fault and shorted-resistor detection. Ideal for power distribution, substations and industrial plants where IEC 61850 communications and reliable ground-fault protection are required.
Key Features
- Continuous NGR monitoring with fast detection of resistor failures to reduce transient overvoltage risk.
- Shorted NGR and ground-fault detection plus selectable pickup sensitivity adjustable in 1% steps (2–100%).
- Adjustable trip/time delay (0.1–10 s) for system coordination and nuisance-filtering.
- Universal CT compatibility, programmable relay outputs and selectable fail-safe or non-fail-safe contact modes.
- Analog 4–20 mA output and pulsing output (SE-330 specific), with front-panel reset or remote N.O. reset contact.
- Built-in harmonics filtering and communication options including USB and dual RJ45 Ethernet with IEC 61850 support.
