The Littelfuse Startco NGRUS336 is a neutral grounding resistor system for 4160 V line-to-line, 2400 V line-to-neutral systems, limiting ground-fault current to 25 A (continuous rating).
A neutral grounding resistor holds the current of a line-to-ground fault to a safe, known value, so a resistance-grounded system can keep running on the first fault while the monitor finds it.
Supplied as: Neutral Grounding Resistor System (NGR, current transformer and sensing resistor in a NEMA 3R enclosure). Resistance: 96.2 Ω (+/- 10 % resistance). Monitor: SE-330. Current transformer: 5SHT-101-E. Sensing resistor: ER-5KV.
Enclosure: NEMA 3R, galvanized steel, NEMA 3R. Finish: powder coated. Insulation level: 75 KV BIL. Temperature rise: 385 °C (725 °F). Seismic bracing: included. Size: Drawing (in): front view 42; right side view 52; height 45; top view 60 x 50; bottom 5/8 dia. mtg. holes on 28 1/4 x 49; (3) 1 1/2 conduit K.O..
Approvals: cULus or CSA at customer request.
