Westinghouse | LB2400 | Circuit Breaker | 400A | 2-Pole | 600V | Bolt-On

Meet the Westinghouse LB2400 circuit breaker—a purpose-built solution for dependable, high-current protection in demanding electrical environments. With a 400A rating and a 2-Pole design, it provides coordinated shutdown for both live conductors on 600V circuits, making it ideal for maintenance, retrofit, or replacement projects where accuracy and reliability matter.

• 400A protection handles demanding loads such as large motor circuits, heating equipment, and other high-current applications common in commercial and industrial settings.
• 2-Pole configuration interrupts both hot legs simultaneously, ensuring safer service and adherence to standard electrical practice for dual-line protection.
• 600V maximum voltage supports a wide range of commercial and industrial installations that operate at higher voltage levels.
• Bolt-On mounting offers a straightforward, field-installable mounting option within compatible panels, supporting quick replacements or retrofits.
• Authentic Westinghouse LB2400 model identified by the LB2400 part number, a reliable reference point for compatibility in existing systems.

Compatibility and ordering guidance: The LB2400 part number is the best reference for ensuring a proper fit. Always confirm the breaker’s amperage, pole count, and voltage ratings match your panel specifications before ordering to avoid mismatches.
