Description
Littelfuse SE-330-20-01 is a versatile relay with multiple configurations and applications. It supports frequencies of 50, 60, and ASD, and has conformal coating for added protection. With various relay contact configurations and fail-safe/non-fail-safe operation, it meets different system requirements. It offers a reset option via front-panel switch or remote N.O. contact. It also features harmonic filtering, a resistance grounded AC system, and has a wide supply voltage range. The relay supports latching and autoreset modes, offers USB communications, and provides analog output current. It has RF trip levels and times suitable for systems up to 5kV and over 5kV. The new revision is available now, while the old revision is no longer available. The relay's ground fault trip level range is 2-100% of the CT-Primary rating.
