Littelfuse SE-330HV-08-00 Neutral Grounding Resistor (NGR) Monitor, universal AC/DC supply (AC 65–265 V, DC 85–275 V). Genuine Littelfuse unit — fast delivery across Indonesia & Southeast Asia from our Batam warehouse.
Littelfuse SE-330HV-08-00 is a Neutral Grounding Resistor (NGR) monitor engineered for continuous supervision and protection of resistance-grounded AC systems. With universal AC/DC supply (AC 65–265 V, DC 85–275 V), programmable relay outputs, analog 4–20 mA and pulsing output plus USB and IEC 61850 communication, the SE-330HV suits substation automation and protection relay schemes. Ideal for utilities, distribution substations, power plants and industrial motor control centers requiring reliable NGR monitoring and IEC 61850-enabled integration.
Key Features
- Continuous NGR monitoring with fast detection of shorted resistor and neutral ground faults.
- Adjustable pickup 2–100% (selectable in 1% steps) to set sensitivity without false trips.
- Adjustable trip/time delay 0.1–10 s for coordination with upstream protection.
- Multiple outputs: 2 Form A and 2 Form C programmable relay contacts, analog 4–20 mA and pulsing output for diagnostics.
- Modern communications including USB, IEC 61850 and dual SC fibre for seamless substation integration.
- Universal CT compatibility, resistance-grounded AC system support, with front-panel or remote N.O. contact reset options.
