Littelfuse SE-701-0D
SE-701-0D is a ground-fault monitor with a supply voltage dc of 12–24 and is uniquely suited for systems with significant harmonic content.
Supporting Information
- Adjustable pickup (1 to 99%) trip setting based on input CT primary, allows use with any CT, minimum 50 mA with EFCT series|Adjustable time delay (50 ms to 2.5 s) - adjustable trip delay allows quick protection and system coordination|Form A and form B ground fault output contacts for operation of separate annunciation and trip circuits|Analog output (0 to 5 VDC) allows for connecting an optional meter (PGA-0500) or a control system|CT-loop monitoring - alarms when CT is not connected|Selectable DFT or peak detection filtering compatible with variable-speed drives|Harmonic filtering eliminates nuisance tripping|Non-volatile trip memory retains trip state when de-energized to simplify troubleshooting|No calibration required, saves on maintenance cost|Universal power supply allows operation in application where one side of PT is faulted, provides flexibility for numerous applications
