B-LINE JGH2250NN – Frequently Asked Questions
1) Does the Eaton Series G JGH2250NN come with a trip unit, or do I have to order one separately?
JGH2250NN is a frame only, with no trip unit included. You order the rating plug/trip separately to set the actual trip current. If you need a complete breaker out of the box, this is not the catalog number to buy.
2) What is the interrupting rating of the Eaton Series G JG-frame 250A breaker frame at 480V?
The JGH2250NN is rated 65 kAIC at 480 Vac. Across the rest of the voltage range it is 100 kAIC at 240 Vac, 70 kAIC at 415 Vac, and 25 kAIC at 600 Vac. Check the available fault current at your panel against the voltage you are actually running before you spec it.
3) Is the Eaton JGH2250NN a two-pole or three-pole breaker frame?
Two-pole. The JG-frame JGH2250NN is built for two-pole applications at up to 600V, so it will not serve a three-phase three-wire load on its own.
4) Will a 250A Series G JG-frame breaker fit my enclosure or panel cutout?
Plan around 7 inches high by 4.13 inches wide by 3.57 inches long and about 6 pounds. That is the frame body alone, so allow extra depth for the trip unit, any accessories, and cable bending space at the lugs before you commit to a shallow enclosure.
5) What amp frame is the Eaton Series G JGH2250NN, and can it be set lower than 250A?
It is a 250A JG-frame. The 250 is the frame's maximum continuous rating, not a fixed trip setting, because the unit ships without a trip. The trip unit and rating plug you pair with it determine the actual trip current, which can be below the 250A frame ceiling.
6) Can I use the Eaton JGH2250NN on a 600V system?
Yes, the frame carries a 600V rating, but the interrupting capacity drops to 25 kAIC at 600 Vac compared with 100 kAIC at 240 Vac. On a 600V service, verify the available fault current is within 25 kAIC or select a higher-interrupting frame.
7) Where do I find the full specifications for Eaton catalog number JGH2250NN?
Eaton publishes a spec sheet for JGH2250NN, and it is linked directly from the product information for this molded case circuit breaker frame. Order by the catalog number JGH2250NN to get the two-pole, 250A, 600V JG frame.
