J-Frame Circuit Breakers

Industrial molded case circuit breakers (MCCBs) with adjustable trip settings designed for overcurrent protection and reliable power distribution in electrical panels and industrial control systems.

J-Frame circuit breakers from Schneider Electric’s Square D PowerPact series are designed to provide dependable overcurrent protection for commercial and industrial electrical systems. These molded case circuit breakers are commonly used in applications that require reliable performance, compact installation, and flexible protection options for medium to heavy electrical loads. With current ratings ranging from 100 to 250 amps, J-Frame breakers are well-suited for distribution equipment, control panels, and machinery protection.

Square D PowerPact J-Frame circuit breakers are available with both thermal-magnetic and electronic trip units. Thermal-magnetic trip units provide dependable protection against overloads and short circuits, while electronic trip units offer adjustable settings for long-time, short-time, instantaneous, and ground-fault protection. This range of trip options allows users to select a breaker configuration that aligns with specific system requirements and coordination needs.

The compact design of J-Frame circuit breakers helps conserve panel space while supporting straightforward installation and maintenance. Available mounting options may include plug-on, bolt-on, or draw-out styles depending on the model and application.
