B-LINE JGS4100AAG – Frequently Asked Questions

1) What is the interrupting rating of the Eaton Series G JGS4100AAG 100A breaker at 240, 480 and 600 volts?
The JG-frame Series G breaker is rated 85 kAIC at 240 Vac, 35 kAIC at 480 Vac and 18 kAIC at 600 Vac. Pick the number that matches your system voltage, then compare it against the available fault current at the point of installation. If your short circuit study calls for more than 18 kAIC on a 600 Vac system, this frame will not cover you.
2) Can the trip settings on the Eaton JGS4100AAG be adjusted in the field?
Yes, both halves. JGS4100AAG uses an adjustable thermal and adjustable magnetic trip, so the overload (thermal) and the instantaneous (magnetic) pickup can each be set rather than being fixed at the 100 A frame rating. That is what makes it usable for motor and feeder circuits where inrush would nuisance-trip a fixed-trip breaker.
3) Will a four-pole 100A JG breaker work on a 480Y/277V three-phase four-wire feeder?
Yes. The Series G JG breaker is rated 600 Vac and 250 Vdc at 50/60 Hz, so 480Y/277 is inside its voltage range, and the four-pole construction gives you a switched conductor for each phase plus the fourth pole. Interrupting capacity at 480 Vac is 35 kAIC.
4) Is the JGS4100AAG a complete breaker or just a trip unit that needs a frame?
It ships as a complete breaker, JG frame, four-pole, 100 A, with line and load terminals included. You are not buying a trip unit that has to be married to a separate frame.
5) What are the dimensions and weight of the Eaton Series G JG 100A four-pole breaker for panel layout?
It measures 7 in high, 5.34 in wide and 3.44 in deep, and weighs 8 lb. Use the 5.34 in width and 3.44 in depth when you are checking gutter space and cover clearance in an existing enclosure before you commit.
6) Can this 100A molded case breaker be used on a DC circuit?
It carries a 250 Vdc rating alongside the 600 Vac rating, so DC applications up to 250 volts are within its ratings. The published interrupting figures (85 kAIC at 240 Vac, 35 kAIC at 480 Vac, 18 kAIC at 600 Vac) are AC values, so size your DC application against the DC withstand data for the JG frame, not against those AC numbers.
