Description
Littelfuse SE-330HV-25-01 is a conformed coated device capable of frequency operation at 50Hz, 60Hz, and ASD. It features relay contacts configuration of 1 Form A, 1 Form B, or 2 Form C, with fail-safe or non-fail-safe operation. The device supports IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86. It offers front-panel or remote N.O. contact reset options and includes standard harmonic filtering. The system type is resistance grounded AC, with supply voltages ranging from 28-52V AC and 36-72V DC. The device is available with latching or autoreset options, and supports communication through USB or Ethernet (Dual SC Fiber). It provides analog output current of 4-20mA and RF trip levels of 100-10000V for systems up to 35kV or 200-20000V for 72kV systems. The new revision is available now, while the old revision is no longer available. The GF trip levels range from 2-100% of CT-Primary Rating.

Features
Continuous NGR monitoring
Shorted NGR detection
Ground-fault detection
Adjustable pickup (2–100 %)
Adjustable time delay (0.1–10 s)
Universal CT compatibility
Programmable output contacts
Selectable contact operating mode
Analog output (4–20 mA)

Detects resistor failure within seconds, reduces transient-overvoltage risk, removes risk of ground-fault detection failure
Detects a ground fault on the neutral that could bypass the resistor, ensures fault current is not higher than expected
Main or backup protection to detect a ground fault anywhere on the monitored system
Select greatest sensitivity without false operation, adjustable in 1 % increments
Adjustable trip delay allows quick protection and system coordination
