Product Training Product Safety Product Guides Product News Featured ProductsIf you manage electrical systems that require larger current capacity, you’ve probably found that regular circuit breakers frequently fall short. Square D’s PowerPacT P-Frame Circuit Breaker specifications bridge this gap by providing reliable protection for systems calling for up to 1200 A and 600 VAC.
This series is designed for applications where conventional Square D PowerPacT breakers, like the H-Frame (150 A) and J-Frame (250 A), simply cannot satisfy the greater amperage requirements for facility energy management.
Features of Square D P-Frame Breakers
Current ratings ranging from 100 A to 1200 A: The PowerPacT P-Frame series for electrical overload protection can handle current ratings ranging from 100 A to 1200 A, as well as voltage levels of up to 600 VAC. This means your electrical distribution system can handle high-demand operations while maintaining safety and performance.
Micrologic electronic trip units: The combination of innovative Micrologic electronic trip units provides accurate protection with programmable settings for long-term, short-term, and immediate trip modes. The flexibility allows you to tune the breaker’s responses to individual system requirements, improving both safety and efficiency.
2, 3, and 4-pole versions: P-Frame breakers, available in 2, 3, and 4-pole versions, give you flexibility for various system designs. Whether you’re working on a complex industrial setting or a huge commercial operation, you’ll get a smooth integration with your existing equipment.

Applications for PowerPacT P-Frame Breakers
Industrial and industrial facilities: Imagine managing an industrial plant with heavy machinery running around the clock. P-Frame breakers protect your equipment against overloads and short circuits, reducing downtime In multi-story office buildings with tenants, P-Frame breakers guarantee each floor has consistent power preventing electrical problems affecting corporate operations.
Healthcare Facilities: Consider a hospital where life-saving equipment relies on an uninterrupted power supply. P-Frame breakers provide the necessary protection to keep critical devices operational, maintaining patient safety and compliance with stringent healthcare regulations.
Data Centers: Even a slight power outage in a data center that manages enormous amounts of information could end in catastrophic data loss. Using P-Frame breakers helps to maintain a steady power environment, protecting servers and storage devices from electrical disturbances.
Energy Infrastructure: Power plants and transportation hubs need effective management of high-capacity electrical systems. P-Frame breakers provide the dependability needed to handle these large activities, maintaining safety and efficiency.
Benefits of Choosing Square D PowerPacT P-Frame
Enhanced Safety: The P-Frame breakers combine sophisticated safety features like changeable trip settings and ground-fault prevention. These components work together to identify and respond to electrical faults quickly, lowering the risk of equipment damage and providing a safer working environment.
Cost-Effective Performance: Because of their high interrupting ratings and sturdy design, P-Frame breakers reduce the chance of electrical failures and related repair expenses. Their dependability means long-term savings, making them an affordable option for your electrical protection requirements.
Ease of Use: P-Frame breakers have common mounting holes, consistent handle placements, and standardized trim dimensions, making installation easier. This consistency minimizes setup time and enables easy integration with various kinds of systems, improving overall user simplicity.
