| Datasheet | Download Datasheet |
The Littelfuse Startco SE-704-0D-CC is an earth-leakage monitor with a 12/24 V dc supply.
It provides sensitive ground-fault protection for resistance- and solidly-grounded systems; marina/boatyard feeder circuits with shunt-trip breaker.
Settings: 10 mA-5.0 A. Trip delay: 30-2000 ms. Sensing: ELCT30 or SE-CS30 series zero-sequence CT (required); CT-loop monitoring.
Outputs: isolated Form A and Form B; selectable fail-safe or non-fail-safe. Analog output: 0-5 V & 0-1 mA. Harmonic filtering: standard feature.
Mounting: DIN, surface (standard); panel (with PMA-55 or PMA-60 adapter). Size: H 75 mm (3.0"); W 55 mm (2.2"); D 115 mm (4.5").
