The Schneider Electric Square D PJA36080CU31A is a Powerpact molded case circuit breaker designed for primary overcurrent protection in industrial power distribution systems. It is a 3-pole, 800A rated device with a solid-state Micrologic 3.0 trip unit providing LI (Long-Time and Instantaneous) protection functions, operating at a maximum voltage of 600V and an interrupting capacity of 65kA at 480V. This P Frame breaker features a lug-in/lug-out connection with AL800M23K terminals, accommodates wire sizes from 3/0 AWG to 500 kcmil (copper/aluminum), and measures 12.86 in x 8.27 in x 8.05 in (H x W x D) with a weight of 32 lb. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, with a temperature rating of 13-158 °F (-25-70 °C) and ABC phase connection. Typical applications include main or feeder protection in switchboards, panelboards, and motor control centers within commercial and industrial facilities.
