Littelfuse SE-330-08-00 Neutral Grounding Resistor (NGR) Monitor — universal AC/DC supply (65–265 VAC / 85–275 VDC), IEC 61850-capable protection relay for resistance-grounded systems. Genuine Littelfuse product with fast delivery from Batam across Indonesia & Southeast Asia.
The Littelfuse SE-330-08-00 is a Neutral Grounding Resistor (NGR) monitor designed for protection and continuous supervision of resistance-grounded AC systems. This IEC-capable protection relay supports universal AC/DC supply voltages (65–265 VAC / 85–275 VDC), offers IEC 61850 and USB communications, and provides RF-trip detection for systems up to and above 5 kV. Ideal for substation neutral monitoring, generator neutrals and industrial motor/transformer protection.
Key Features
- Continuous NGR monitoring with shorted-resistor detection
- Selectable contact operating modes: fail-safe or non-fail-safe; latching or autoreset
- Flexible I/O: 2 Form A or 2 Form C programmable outputs
- Communications: USB and IEC 61850 for integration with modern protection systems
- Adjustable pickup (2–100 %) and adjustable trip delay (0.1–10 s) for coordination
- Analog 4–20 mA output and pulsing output (SE-330 models) plus conformal coating for harsh environments
