Description
Littelfuse® Ground Fault Relay, Microprocessor Based, Series: SE-701, 120/240 VAC, 0.05 to 2.5 s Response Delay, 0 to 5 V Analog Output, 1 to 99% CT Primary Rating Trip Level Settings, Surface Mount, 3 in H x 2.2 in W x 4.5 in D
Features:
- Adjustable pickup - trip setting based on input CT primary, allows use with any CT, minimum 50 mA with EFCT series
- Adjustable time delay - adjustable trip delay for quick-protection and system coordination
- Output contacts form a and form B ground fault output contacts for operation of separate annunciation and trip circuits
- Analog output 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 while de-energized to simplify troubleshooting
- Microprocessor based - 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
Standards/Approval:
- PROP65: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer
