Description
Littelfuse SE-330AU-21-01 is a conformally coated relay with multiple contact configurations (1 Form A, 1 Form B, 2 Form C) and fail-safe operation. It is suitable for resistance grounded AC systems. The device supports a wide supply voltage range and allows for front-panel switch or remote N.O. contact reset. In addition, it offers standard harmonic filtering, USB and DeviceNet communication capabilities, and analog output current of 4-20 mA. The GF trip level ranges from 0.125 to 30.0 A, while the RF trip level varies from 20 to 2000 V for systems up to 5 kV and 100 to 10,000 V for systems over 5 kV. The RF trip time is set at 12 seconds. The new revision of this product 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.
