PJA36080CU43CE1ACSA

The PJA36080CU43CE1ACSA is a 3-pole electronic molded case circuit breaker (MCCB) from Schneider Electric' PowerPacT P-frame family, engineered for high-current industrial and commercial power-distribution applications requiring advanced electronic overload and short-circuit protection. Rated for 800 at , this 100%-rated I-Line breaker uses a MicroLogic 5.0A electronic trip unit to provide precise circuit protection, selective coordination, and current monitoring for main, feeder, and distribution applications. Electrically, the PJA36080CU43CE1ACSA provides long-time, short-time, and instantaneous (LSI) protection through its MicroLogic electronic trip system. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination during elevated fault currents, and instantaneous protection provides rapid interruption of severe short-circuit conditions. It carries an interrupting capacity of , providing high fault-current capability for demanding commercial and industrial distribution systems. The configuration also incorporates Modbus communications for integration with compatible monitoring and energy-management systems. Mechanically, the PJA36080CU43CE1ACSA uses Schneider Electric' I-Line plug-in bus connection for direct installation in compatible switchboard and distribution equipment. Its 3-pole common-trip construction provides coordinated disconnection of all protected phases when the electronic trip unit detects a qualifying fault condition. Factory-installed accessories include a 3a3b auxiliary switch for breaker-position and control signaling and a 110–130 V AC shunt trip for remote electrical opening from emergency-shutdown, interlock, or equipment-control circuits.
