Meet the Square D MA26450 circuit breaker—a robust, high-current protection device designed for demanding electrical environments. With a 450A rating, 2-pole configuration, and a 600V maximum, this unit delivers reliable interruption and safeguards feeders and motors against overloads and faults in industrial and commercial settings.
Built for maintenance, retrofit, and replacement projects, the MA26450 is your best reference for compatibility. Before you order, verify fit and ratings against your panel documentation; the part number MA26450 is the most dependable guide to ensure a precise match.
Key reasons this breaker stands out
- High-current protection: 450A capacity supports large loads common in industrial panels, manufacturing lines, and high-demand equipment feeders.
- Two-pole design: Simultaneous disconnection of both hot legs enhances safety and protective coordination across the circuit.
- 600V rating: Suitable for typical industrial distribution systems, reducing voltage-related protection uncertainties.
- OEM-grade reliability: Engineered to meet Square D standards for consistent operation and seamless compatibility with Square D enclosures.
- Retrofit-friendly: Thoughtful form factor and mounting alignment simplify swaps in existing Square D installations, minimizing downtime.
Ideal use cases
- Replacing a failed 450A/2-pole breaker in main or sub-panels within factories, warehouses, or large facilities.
- Upgrading circuits to support higher-capacity motors, conveyors, or other heavy equipment in manufacturing environments.
- Retrofitting legacy electrical systems that require exact MA26450 specifications to maintain protective integrity.
Practical installation notes
- Always confirm fit and ratings with your panel’s documentation; MA26450 is your strongest reference for compatibility.
- Handle with care during replacement to protect bus connections and the surrounding panel components.
- Store and install in a dry, clean environment to preserve long-term performance and reliability.
