HJA36150U31X6

The HJA36150U31X6 is a 3-pole electronic molded case circuit breaker (MCCB) from Square D, Schneider Electric' PowerPacT H-frame family, engineered for industrial and commercial power-distribution applications requiring adjustable electronic overload and short-circuit protection. Rated for 150 at , this I-Line breaker uses a MicroLogic 3.2 electronic trip unit to provide precise circuit protection and coordination for feeder, branch-circuit, and equipment applications. Electrically, the HJA36150U31X6 provides long-time and instantaneous (LI) protection through its MicroLogic electronic trip system. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid interruption during severe short-circuit faults. It carries an interrupting capacity of , providing high fault-current capability for demanding commercial and industrial distribution systems. The electronic trip architecture allows more precise pickup and delay adjustment than conventional fixed thermal-magnetic protection. Mechanically, the HJA36150U31X6 uses Square D, Schneider Electric' I-Line plug-in bus connection for direct installation in compatible panelboard and distribution equipment. Its 3-pole common-trip construction provides coordinated disconnection of all protected phases when the MicroLogic trip unit detects a qualifying fault condition. The compact PowerPacT H-frame design supports space-efficient installation and compatible load-side conductor connections while meeting applicable UL 489, CSA, NEMA, IEC, and related certification requirements.
