Description
Littelfuse SE-330AU-24-00 is a conformally coated relay with 2 Form A and 2 Form C contacts. It operates as a fail-safe with IEEE Device Numbers 50G-50N-51G-51N-59N-86. It can be reset using a front-panel switch or a remote N.O. Contact. It offers standard harmonic filtering and is suitable for resistance grounded AC systems. It operates on supply voltages of 28-52V AC and 36-72V DC. It can be auto-reset or latching. It offers USB and Ethernet communication options, along with analog output current of 4-20mA. It provides GF trip levels of 0.125-30.0A and RF trip levels of 20-2000V (systems up to 5kV) and 100-10000V (systems over 5kV). The RF trip time is 12 seconds. The new revision is now available, while the old revision is no longer available.

Features
The SE-330AU series is an advanced earth-fault and earthing-resistor monitoring relay for low- and medium-voltage transformers and generators. It monitors neutral current, neutral-to-earth voltage, and neutral-to-earth resistance. It provides continuous monitoring of the neutral-to-earth path to verify that the neutral-earthing resistor (NER) is intact. An open NER renders current-sensing, earth-fault protection inoperative and could result in a false belief that the system is functioning properly.
