Description
Littelfuse SE-330HV-28-00 is a conformally coated relay with 2 Form A and 2 Form C contacts. It operates in fail-safe or non-fail-safe mode with IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86. Reset can be done through a front-panel switch or remote N.O. contact. Harmonic filtering is standard. It has a GF trip time range of 0.1-10.0s. The supply voltage is 28-52VAC and 36-72VDC. It is available in latching or autoreset mode. Communications options include USB and IEC61850. It has an analog output current range of 4-20mA. The RF trip level range is 100-10000V for systems up to 35kV and 200-20000V for 72kV systems. The new revision is available now, while the old revision is no longer available. The GF trip level range is 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
