Littelfuse SE-701-0U Ground Fault Relay
Part #:SE-701-0U
SKU #: 2309448
Key Features
Part #:SE-701-0U
SKU #: 2309448
Brand: Littelfuse
Analog Output: 0 to 5, 0 to 5 V
Dimensions: 3 in H x 2.2 in W x 4.5 in D
Response Delay: 0.05 to 2.5, 0.05 to 2.5 s
Series: SE-701
Specifications: 1 to 99% CT Primary Rating Trip Level Settings
- 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

Catalog Description: The SE-701 is a microprocessor-based ground-fault relay for resistance and solidly-grounded systems. In addition to common systems, it is uniquely suited for use on systems with significant harmonic content. The SE-701 can provide main-plant protection, feeder-level protection, or individual-load protection. Proper current transformer selection provides the desired pickup range. The output contacts can be connected for use in protective tripping circuits or in alarm indication circuitThe SE-701 is a microprocessor-based ground-fault relay for resistance and solidly-grounded systems.
