Product FAQs
6 answersCan the JGS3250FAG replace an older Series C J3250 breaker?
Yes, you can use the JGS3250FAG to replace legacy Series C J3250 breakers, but you will need a specific mounting adapter to properly align the newer Series G frame within the older enclosure.
Will the JGS3250FAG fit into a standard residential load center?
No. This JG-frame breaker is intended for commercial and industrial power distribution. It is specifically designed for Eaton Series G panelboards, switchboards, and motor control centers.
What is the adjustable magnetic trip range on the JGS3250FAG?
The instantaneous magnetic trip unit can be adjusted from 1250 A to 2500 A for precise short-circuit coordination. The thermal overload trip is fixed at 250 A.
Is the JGS3250FAG rated for direct current (DC) systems?
Yes, this breaker carries a DC rating of up to 250VDC with an interrupting capacity of 22 kAIC.
Does this breaker come with line and load lugs installed?
Yes, it includes standard line and load lugs that accept 4 AWG through 350 kcmil copper or aluminum conductors.
How does the unit-mount design of the JGS3250FAG differ from a bolt-on breaker?
As a feed-thru unit-mount breaker, it fastens directly to a chassis, backpan, or mounting plate using metric hardware, rather than bolting directly onto the live bus bars of a traditional panelboard.
