| Datasheet | Download Datasheet |
The Littelfuse Startco PGR-4700-240 is a sensitive ground-fault relay with a 240 Vac supply.
It provides sensitive ground-fault (leakage) protection on solidly grounded systems.
Settings: 10 mA – 3.0 A. Trip delay: 0–1.5 s. Sensing: PGC-5000 series zero-sequence ground-fault CT (required); CT loop monitoring.
Outputs: 2 Form C; selectable fail-safe or non-fail-safe (internal switch). Communications: Analog Output. Harmonic filtering: standard.
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”). Conformal coating: consult factory.
Approvals: Not available with UL.
