B-LINE JGS4200AAG – Frequently Asked Questions

1) Will the B-Line JGS4200AAG 200A breaker hold up on a 480V system with high available fault current?
The JG frame 200A breaker is rated 35 kAIC at 480 Vac, with 85 kAIC at 240V, 40 kAIC at 415V and 18 kAIC at 600V. Compare those figures against the available fault current at your point of installation. If your 480V service study shows more than 35 kA available, this breaker is not the right choice on its own.
2) Can I fine-tune the trip settings on the B-Line JG frame 200A breaker, or is it fixed?
Both the thermal and the magnetic elements are adjustable on the JGS4200AAG. That lets you dial the overload pickup down from the 200A frame rating to match the actual conductor ampacity, and set the instantaneous magnetic pickup to ride through motor inrush without nuisance tripping. Useful when you are coordinating with downstream devices.
3) Does the B-Line Series G JG breaker come with lugs, or do I order terminals separately?
Line and load terminals are included, so the breaker ships ready to land conductors at both ends. Mounting hardware is metric, which matters if you are fitting it into an enclosure or panel drilled for imperial hardware. It is supplied as a complete breaker, not a frame-only or trip-unit-only item.
4) Is this B-Line 200A breaker UL Listed and acceptable for a 600V system?
It is UL Listed and CE Marked, and rated to 600 Vac. That covers 600V, 480V, 415V and 240V systems, with the interrupting rating dropping as system voltage rises, down to 18 kAIC at 600V.
5) How much space do I need in the panel for a B-Line JG frame 200A molded case breaker?
Plan on 5.34 in by 5.34 in of face area with a 3.57 in depth behind the mounting surface. It weighs 8 lb, so a four-pole unit at this size wants proper support and two hands going into a live-front enclosure.
6) What part number do I quote for the B-Line Series G four-pole 200A JG frame breaker?
Order it as B-Line JGS4200AAG. That code covers the JG frame, 200A rating, four poles with a 0% protected neutral, line and load terminals and the adjustable thermal-magnetic trip.
