Description
Littelfuse SE-330AU-20-01 is a conformally coated relay with multiple contact configurations (1 Form A, 1 Form B, 2 Form C). It operates as a fail-safe device with IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86. The reset type can be done through a front-panel switch or remote N.O. contact. It offers standard harmonic filtering, a GF trip time of 0.1-0.5 seconds, and a supply voltage of 28-52 VAC or 36-72 VDC. It has latching or autoreset options, USB communication, analog output current range of 4-20 mA, RF trip level of 20-2000V (for systems up to 5 kV) or 100-10000V (for systems over 5 kV), and a RF trip time of 12 seconds. It is available in the new version now, while the old version 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.
