Westinghouse | LA2400F | Circuit Breaker | 400A | 2-Pole | 600V

The Westinghouse LA2400F Circuit Breaker is engineered for demanding electrical systems where dependable overcurrent protection matters most. Built for maintenance, retrofit, and replacement projects, this 400A, 2-pole unit delivers the reliability you need to keep circuits safe and service interruptions at bay.

• Amperage: 400A
• Poles: 2-Pole
• Voltage rating: 600V
• Part number: LA2400F — the clearest reference for compatibility
• Best-use scenarios: maintenance, retrofit, and replacement where matching specs are required

Why choose the LA2400F for your panel? This breaker is purpose-built to align with Westinghouse legacy configurations, offering a direct replacement path when you need to restore full protection without guesswork. The 2-pole design ensures both conductors in a circuit are protected and disconnected together, enhancing safety in higher-current applications and multi-wire branch circuits.

Ideal use cases

• Repairing aging panels that require a 400A, 2-pole, 600V device
• Retrofitting existing electrical systems to meet current protection standards
• Replacing a faulty or worn-out breaker in commercial, industrial, or large residential setups
• Replacing in projects where the LA2400F designation is the explicit compatibility requirement

Key considerations for a smooth fit

Before ordering, verify that your panel labeling aligns with the LA2400F specification. The part number is the most reliable reference for compatibility, so use it as your primary cross-check. For safe and reliable installation, have a licensed electrician confirm that the panel’s ratings and bus compatibility match the LA2400F requirements.

What sets this apart

Unlike generic, one-size-fits-all breakers, the Westinghouse LA2400F is designed to integrate with systems that specifically call for this part number. This means fewer surprises during installation, quicker updates to aging panels, and a clarified path for ongoing maintenance and compliance. With 400A capacity, it handles substantial load protection while preserving system safety across two conductors in a single unit.
