Description
Littelfuse SE-330-25-01 is a conformally coated relay with various frequency options (50; 60; ASD) and relay contact configurations (1 Form A; 1 Form B; 2 Form C). It operates as fail-safe or non-fail-safe and has IEEE device numbers (50G, 50N, 51G, 51N, 59N, 86). It supports both front-panel and remote N.O. contact reset types and offers standard harmonic filtering (DFT). The system type is resistance grounded AC, with supply voltage ranges of 28-52V AC and 36-72V DC. Additional features include latching or autoreset options, USB and Ethernet (Dual SC Fiber) communications, 4-20mA analog output current, RF trip level ranges of 20-2000V (for systems up to 5kV) and 100-10000V (for systems over 5kV), a 12s RF trip time, and availability of the new revision. The old revision is discontinued. GF trip level ranges from 2-100% of CT-Primary Rating.

Coil Voltage Rating
28-52 Volt
Coil Voltage Rating
36-72 Volt (DC)
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
