Description
Littelfuse SE-330-07-00 is a conformally coated relay with 2 Form A and 2 Form C contacts, suitable for fail-safe or non-fail-safe operations. It features IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86 and offers front-panel or remote N.O. contact reset options. The device supports resistance grounded AC systems, with supply voltages ranging from 65-265 VAC and 85-275 VDC. It includes standard harmonic filtering and is available with latching or autoreset function. The SE-330-07-00 provides USB and IEC61850 communication options and offers 4-20 mA analog output current. RF trip levels vary from 20-2000 V for systems up to 5 kV and 100-10000 V for systems over 5 kV. The trip time is 12 seconds. The new revision of the product is currently available, while the old revision is no longer available. The device has a ground-fault trip level range between 2-100% of CT-Primary Rating.

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
