Littelfuse SE-330-03-00 is a versatile relay with multiple configuration options. It has a frequency range of 50Hz, 60Hz, and ASD. The relay is conformally coated for protection and has 2 Form A and 2 Form C contacts. It can operate in fail-safe or non-fail-safe mode and features IEEE device numbers 50G, 50N, 51G, 51N, 59N, and 86. The reset can be done through a front-panel switch or remote N.O. contact. It also has standard harmonic filtering and is suitable for resistance grounded AC systems. The relay's supply voltage ranges from 65V to 265V AC and 85V to 275V DC. It has latching or autoreset options for reset and supports USB and Ethernet communications. The analog output current ranges from 4mA to 20mA, and the RF trip level ranges from 20V to 2000V for systems up to 5kV and 100V to 10000V for systems over 5kV. The RF trip time is 12 seconds. The new revision of the relay is now available, and the old revision is no longer available. The GF trip level range is from 2% to 100% of the CT-primary rating.
