Description
Littelfuse SE-330-00-00 is a conformally coated relay with 2 Form A; 2 Form C contacts. It operates in fail-safe or non-fail-safe mode and has a front-panel switch or remote N.O. contact reset type. It provides standard harmonic filtering and supports resistance grounded AC systems with supply voltages of 65-265V AC and 85-275V DC. It offers latching or autoreset for reset functionality, USB communication, and 4-20mA analog output current. The RF trip level ranges from 20-2000V for systems up to 5 kV and 100-10000V for systems over 5 kV. It has a RF trip time of 12s and a GF trip time ranging from 0.1-10s. It is compatible with IEEE device numbers 50G - 50N - 51G - 51N - 59N - 86 and has a GF trip level range of 2-100% of CT-Primary Rating. The new revision is now available, replacing the old version.

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
