The LIP26450 is designed for use where exact specifications are required, making it a reliable drop-in option for compatible Square D panels and systems.

• Amperage: 450A
• Poles: 2-Pole
• Voltage: 600V

Why choose the LIP26450 for your installation

• Precise compatibility — The part number itself is your best reference for compatibility with Square D systems. Use LIP26450 when your panel or distribution plan specifies this model to ensure proper fit and protection.
• Ideal for maintenance, retrofit, and replacement — When upgrading an aging panel or swapping a failed breaker, this unit provides a reliable, exact-match solution that minimizes downtime and reconfiguration.
• Two-pole design for safer disconnection — Simultaneously interrupting both live conductors enhances safety during servicing and reduces the risk of backfeed or arc faults.
• 600V readiness for medium-voltage applications — The 600V rating makes it suitable for a range of commercial and industrial distributions that operate above low-voltage thresholds.
• Quality you can trust — As part of the Square D lineage, this breaker leverages proven design and performance to help protect circuits, equipment, and personnel.

Use cases and scenarios

• Upgrading or replacing breakers in commercial or industrial panels where a 450A, 2-pole, 600V device is specified.
• Retrofit projects where maintaining the original Square D protection scheme is essential for system reliability.
• Spare or replacement stock for maintenance crews managing high-capacity feeders or critical power paths.

Practical installation notes

• Always verify the fit and ratings before ordering — consult your panel’s documentation and confirm that LIP26450 matches the required specifications.
• Ensure the installer is licensed and follows proper torque and connection procedures for a secure, compliant installation.
• Label the updated panel clearly to reflect the new 450A, 2-pole, 600V protection and maintain accurate maintenance records.

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.
