Description
Littelfuse SE-330-08-00 is a conformally coated relay with 2 Form A or 2 Form C contacts. It operates in fail-safe or non-fail-safe modes and can be reset via front-panel switch or remote N.O. contact. With standard harmonic filtering, it's suitable for resistance grounded AC systems. It supports both AC and DC supply voltages and offers latching or autoreset options. Communication options include USB and IEC61850. The RF trip level ranges from 20 to 2000V for systems up to 5kV and 100 to 10000V for systems over 5kV.
