Schneider Electric QJA32150 I Line Circuit Breaker

Schneider Electric's QJA32150 is a PowerPact Q I-Line molded-case circuit breaker designed for 240 VAC three-phase systems. This 3-pole, 150 A device delivers 100 kA interrupting capacity at 240 VAC and employs a thermal‑magnetic trip mechanism to protect feeders from overloads and short circuits in Schneider Electric I‑Line panelboards. As part of the PowerPact Q family, the QJA32150 is a purpose‑built solution for distribution applications that require reliable protection of three‑phase loads, including motors and key distribution feeders, with alignment to ABC (phases A, B, and C) configurations. The unit’s 80% continuous rating supports typical industrial usage, matching common practices for MCCB sizing in commercial and light‑industrial environments. Built to integrate with I‑Line infrastructure, this breaker provides consistent protection characteristics and replacement compatibility within Schneider Electric’s PowerPact lineup, helping ensure predictable coordination with other protective devices and straightforward maintenance in control panels and distribution assemblies.
