Description
Littelfuse SE-330-27-01 is a conformally coated relay device that operates at frequencies of 50, 60, and ASD. It has various relay contact configurations (1 Form A, 1 Form B, 2 Form C) and can be operated in fail-safe or non-fail-safe modes. With IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86, it offers front-panel or remote reset options. It features standard harmonic filtering (DFT), a supply voltage range of 28-52V AC and 36-72V DC, and auto/manual reset capabilities. The SE-330-27-01 offers USB and IEC61850 communications options, with both analog output current and RF trip level ranges. It is available in a new revision and is suitable for resistance grounded AC systems.

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)
Pulsing output (SE-330 only)
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
