Square D | LAP26350 | Circuit Breaker | 350A | 2-Pole | 600V

Meet the Square D LAP26350 circuit breaker—a purpose-built protection device for high-demand electrical systems. With a 350A rating, this 2-pole unit is designed to interrupt and isolate large feeders at up to 600V, delivering dependable protection for heavy equipment, motors, and critical loads in industrial environments.

Designed for maintenance, retrofit, and replacement projects where exact specs matter, LAP26350 aligns with existing Square D panels and assemblies that call for a 2-pole, 350A, 600V breaker. Always confirm fit and ratings before ordering; the part number remains the most reliable reference for compatibility.

Why this breaker stands out

• High-current capacity, streamlined design: 350A rating supports demanding equipment without needing multiple devices, helping simplify panel design and reduce part counts.
• Two-pole protection: Simultaneous interruption of both live conductors ensures safer fault clearing in high-energy circuits.
• 600V class applications: Suited for industrial feeders, distribution panels, and motor control circuits in commercial settings.
• Retrofit-ready: A solid choice for upgrading aging protection in existing installations, minimizing downtime and compatibility risk.
• Clear compatibility reference: Use LAP26350 as the definitive reference when sourcing replacements; verify the fit against your panel label and service requirements.

Practical use cases include upgrading main feeders in manufacturing lines, replacing worn breakers in commercial/industrial panels, or retrofitting old installations to meet current protection standards. This breaker supports reliable outage protection for large motors, conveyors, pumps, and other high-load equipment, helping reduce unplanned downtime and equipment damage.

How to ensure a smooth install and long-term performance:

• Verify that your panel or enclosure accepts a LAP26350-sized breaker and that the voltage and amperage ratings match your electrical design.
• Power down the panel and follow lockout/tagout procedures before replacing any device.
• Consult your equipment manual for installation torque and mounting guidelines; use correct tools and conductor sizing per your spec sheet.
• Inspect for signs of wear or corrosion on the mounting hardware and replace any worn components alongside the new breaker to ensure solid electrical contact.
