Product FAQs
5 answersWhich electrical panels are compatible with the Square D JGA36250U31X?
This breaker fits Square D I-Line panelboards and I-Line switchboards [1.1.2]. It will not install in standard NQ, NF, or QO series panelboards.
How much mounting space does this J-Frame breaker require in an I-Line panel?
This 3 pole breaker requires 4.5 inches of vertical mounting space on an I-Line bus. Each of the three phases occupies 1.5 inches of bus space.
What adjustability does the U31X trip unit provide on this breaker?
The U31X suffix denotes a Micrologic 3.2 electronic trip unit. This allows panel builders and electricians to adjust both the long-time and instantaneous settings for precise load coordination.
Does the JGA36250U31X offer equipment ground fault protection?
No. The standard Micrologic 3.2 trip unit provides only long-time and instantaneous protection. You need a model with an LSIG trip unit, typically indicated by a U54X suffix, for ground fault protection.
What is the replacement load lug kit for the JGA36250U31X?
The standard mechanical load lug kit is Square D catalog number AL250JD. It accepts one 3/0 AWG to 350 kcmil aluminum or copper conductor per phase.
