Description
Littelfuse SE-330AU-26-01 relay is a fail-safe device designed for resistance grounded AC systems. It features 1 Form A, 1 Form B, or 2 Form C relay contacts, with a reset available through a front-panel switch or remote N.O. contact. With a supply voltage of 28-52V AC and 36-72V DC, it offers standard harmonic filtering and supports communication via USB and IEC61850 (Dual RJ45). The relay provides reliable protection with GF trip times of 0.1-0.5 seconds and trip levels of 0.125-30.0A for ground faults and 20-2000V for RF trips (systems up to 5kV) or 100-10000V (systems over 5kV). It also offers analog output current of 4-20mA for monitoring purposes. 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.
