Square D JDP36250 is a molded case circuit breaker designed for providing reliable overcurrent protection in three-phase industrial power distribution systems. It features a 250A current rating and a 600V voltage rating, housed within a compact J-frame measuring 191 mm H x 104 mm W x 86 mm D and weighing 4.839 lb. The breaker utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection, offers an interrupting capacity of 18kA at 480V, and is compliant with UL, CSA, NEMA, and IEC 60947-2 standards. Its bolt-on connection with lug/nut terminals accommodates conductors from 3/0 AWG to 350 kcmil, making it suitable for panelboards, switchboards, and industrial control panels operating in ambient temperatures from -2 to 70 °C.
