Schneider Electric JJA36250U33X Molded Case Circuit Breaker

Schneider Electric’s Square D PowerPact J-frame molded-case circuit breaker, model JJA36250U33X, is a 250 A, three-pole unit built for 600 V systems. As part of the PowerPact J family, it houses a Micrologic 3.2S electronic trip unit with Long-Time, Short-Time and Instantaneous protection and uses I-Line plug-in mounting for straightforward installation in distribution panels. Rated for 600 VAC operation with current-limiting short-circuit protection, it delivers an interrupting capacity of 25 kA at 600 V (65 kA at 480 V), making it suitable for protecting feeders and three-phase circuits in commercial and industrial installations. The device’s 3-pole configuration and Micrologic 3.2S trip are designed for reliable coordination within the PowerPact J family, and the trip is non-interchangeable to maintain consistent protective characteristics. Common applications include protection of feeders and motors in panelboards, switchgear, and motor control centers up to 250 A.
