The JDA36250 Square D 3P 250A 600V 14KA I-Line circuit breaker is designed for reliable performance in demanding applications. With its three-pole configuration, it supports high electrical loads while ensuring safety and efficiency. Ideal for industrial settings, this robust breaker offers superior protection against overloads and short circuits.
No. The JDA36250 uses Square D's I-Line plug-in connection system, which has a distinct bus stab design specific to I-Line panelboards and switchboards. It is not interchangeable with QO, Homeline, or other Square D residential/light-commercial loadcentre styles. Always verify your panelboard accepts I-Line JDA-frame breakers before ordering.
Square D has transitioned many JDA-frame products over the years. Northern Breaker Group specialises in obsolete and hard-to-find breakers, so even if the JDA36250 is no longer in active production, we can often source new-old-stock or reconditioned units. Contact our Calgary, Edmonton, or Vancouver counter for current availability.
At 14 kA AIC @ 600 V, this breaker suits many commercial and light-industrial feeder applications, but some industrial sites with high available fault current may require a higher-rated unit. Square D's JDA frame is available in higher interrupting-capacity variants. Share your fault-current study results with us and we'll help identify the right breaker for your system.
