Schneider Electric JJA36250U33X Circuit Breaker

Schneider Electric JJA36250U33X is a PowerPact J molded‑case circuit breaker rated for 250 A across three poles, designed for up to 600 V AC circuits. It uses an electronic Micrologic 3.2S trip unit with a non‑interchangeable trip mechanism and provides Long‑Time, Short‑Time, and Instantaneous protection for three‑phase loads; the I‑Line design enables plug‑in mounting in compatible panelboards. The device carries interrupting ratings that depend on system voltage: 65 kA at 480 V and 25 kA at 600 V, making it suitable for feeders and motor circuits in industrial and commercial power distributions. This Square D/Schneider Electric MCCB is UL listed and part of the PowerPact J family, ensuring reliable protection with a fixed trip setting rather than user adjustments. With its 3P 250 A rating, it serves as a compact protective device in mechanical rooms, electrical rooms, or switchgear where space is at a premium and fast, accurate fault protection is needed.
