The JJA36250U44XYH2 is a 3-pole electronic molded case circuit breaker (MCCB) from Schneider Electric, Square D' PowerPacT J-frame family, engineered for industrial and commercial power-distribution applications requiring advanced overload, short-circuit, and ground-fault protection. Rated for 250 at 600, this I-Line breaker uses a MicroLogic 6.2A electronic trip unit to provide precise circuit protection, selective coordination, and current monitoring for feeder, distribution, and equipment applications. Electrically, the JJA36250U44XYH2 provides long-time, short-time, instantaneous, and ground-fault (LSIG) protection together with integrated ammeter functionality. Long-time protection responds to sustained overload conditions, short-time protection supports coordination during elevated fault currents, instantaneous protection provides rapid interruption of severe short-circuit conditions, and ground-fault protection responds to qualifying ground-fault current. It carries an interrupting capacity of , providing high fault-current capability for demanding industrial and commercial distribution systems. Mechanically, the JJA36250U44XYH2 uses Schneider Electric, Square D' I-Line plug-in bus connection for 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 YH2 configuration incorporates an external neutral current transformer (ENCT) wiring harness together with wiring for all installed accessories, providing a factory-routed terminal interface for associated control and protection wiring.
