The Littelfuse Startco SE-325DN is a neutral-grounding-resistor monitor with a 120 Vac/dc supply.
It monitors integrity of the neutral-to-ground path (NGR continuity, neutral current and voltage) and detects ground faults; one alarm or trip output contact.
Settings: GF trip level 0.5-4.0 A; GF trip time 0.1-2.0 s; RF trip level 20-400 Vac (≤5 kV systems), 100-2,000 Vac (>5 kV systems). Trip delay: Ground fault 0.1-2.0 s; resistor fault 5 ± 0.5 s; non-latching, resets when the fault clears (Option N). Applications: resistance-grounded systems up to 25 kV. Sensing: CT200 series (required); ER series (required).
Outputs: Form A.
Mounting: surface. Size: H 150 mm (5.9"); W 109 mm (4.3"); D 100 mm (4.0"). Conformally coated as standard.
