The Square D PJA36025CU44A is a 3-pole molded case circuit breaker from the Powerpact family, designed to provide solid-state LSIG (Long-Time, Short-Time, Instantaneous and Ground Fault) protection for industrial power distribution systems. It is rated for 250A at 600VAC, with an interrupting capacity of 65kA at 480V, and operates on a 3-phase system. This P Frame breaker features an I-Line style plug-in connection, measures 12.86 in x 8.27 in x 8.05 in (H x W x D), weighs 32 lb, and accepts wire sizes from 3 x AWG 3/0 to 500 kcmil aluminum/copper via AL800M23K terminals. It is certified to UL, CSA, NOM, and NEMA standards, complying with NOM-003-SCFI-2000 and IEC 60947-2, and is rated for an operating temperature range of 13-158 °F (-25-70 °C). Typical applications include main or feeder protection in switchboards, panelboards, and industrial control panels requiring selective coordination and ground fault detection.
