Schneider PowerPact PJA36080U44A

The Schneider PowerPact PJA36080U44A molded case circuit breaker is a high-performance low-voltage protection device engineered by Schneider Electric under the Square D PowerPact P-frame series. Designed for industrial and commercial electrical distribution systems, this breaker delivers dependable protection against overloads, short circuits, and ground faults while offering advanced monitoring and coordination capabilities for critical power applications.

Rated at 800 A with an operational voltage of up to 600 V AC, the PJA36080U44A features a robust 3-pole configuration suitable for three-phase power systems. The breaker incorporates a MicroLogic 6.0A electronic trip unit with LSIG protection (long-time, short-time, instantaneous, and ground-fault), enabling precise adjustment of protection parameters and improved selectivity with downstream devices. The integrated ammeter function provides real-time current monitoring and diagnostic information, supporting preventive maintenance and system optimization.

Built on the durable P-frame platform, the breaker offers high interrupting capacity ratings—up to 65 kA at 480 V AC and 25 kA at 600 V AC—ensuring safe interruption of fault currents in demanding electrical environments. The I-Line plug-in connection on the line side with mechanical lugs on the load side simplifies installation and integration into switchboards, panelboards, and motor control centers, making it suitable for both new installations and retrofit projects.

The Schneider PowerPact series is recognized for its modular design, allowing compatibility with a wide range of accessories, auxiliary devices, and communication options. Compliance with major international standards such as UL, CSA, IEC, and NEMA ensures reliable operation and global acceptance. With its rugged construction, electronic protection accuracy, and flexible mounting configuration, the PJA36080U44A provides a dependable solution for modern electrical distribution systems that require safety, efficiency, and long-term operational reliability.

Overall, the Schneider PowerPact PJA36080U44A circuit breaker combines advanced protection technology, strong interrupting performance, and installation flexibility, making it ideal for industrial plants, commercial buildings, infrastructure facilities, and critical power distribution networks.
