Littelfuse SE-330HV-01-00 Neutral Grounding Resistor (NGR) Monitor — supply 65–265 V AC / 85–275 V DC, 4–20 mA analog output and DeviceNet/USB communications. Genuine Littelfuse product from Batam with fast delivery across Indonesia and Southeast Asia.
The Littelfuse SE-330HV-01-00 is a neutral grounding resistor (NGR) monitor designed for resistance-grounded AC systems. This protection relay-style device accepts 65–265 V AC or 85–275 V DC supplies, provides a 4–20 mA analog output and supports USB and DeviceNet communications. SE-330HV is used for continuous NGR monitoring, ground-fault detection and rapid resistor-failure alarm in substations, industrial power distribution and utility applications requiring reliable NGR supervision.
Key Features
- Continuous monitoring of neutral grounding resistor with shorted-NGR detection to quickly flag resistor faults.
- Selectable fail-safe or non-fail-safe operation and selectable contact operating modes for flexible control logic.
- Front-panel switch or remote N.O. contact reset, with programmable output contacts and pulsing output on SE-330 models.
- Universal CT compatibility, adjustable pickup (2–100 %) and adjustable trip delay (0.1–10 s) for precise sensitivity and coordination.
- Analog 4–20 mA output plus USB and DeviceNet communications for integration with SCADA and protection systems.
- Conformal coating and standard harmonic filtering for robust performance in industrial environments.
