Square D | MHP26350 | Circuit Breaker | 350A | 2-Pole | 600V

Introducing the Square D MHP26350 Circuit Breaker — a rugged, highly compatible solution built for demanding electrical environments. With a 350A rating, a two-pole design, and a 600V operating capability, this device delivers reliable overcurrent protection for mid-to-large industrial and commercial circuits. It’s an ideal choice for maintenance, retrofit, and replacement projects where exact specs matter.

Key reasons to choose the MHP26350

• Exact part reference: The MHP26350 designation is the best reference for compatibility, helping you replace the right unit in Square D panels and enclosures with confidence.
• Two-pole protection: A true two-pole design ensures coordinated disconnection of both hot conductors, enhancing safety for 600V circuits.
• 350A capacity: Supports high-load applications and large feeders typical in manufacturing floors, data centers, and heavy equipment setups.
• 600V maximum: Suitable for standard industrial and commercial electrical systems that require robust protection at higher voltages.
• Maintenance, retrofit, and replacement: Perfect for updating aging panels, upgrading protection schemes, or restoring service with a trusted Square D component.

Who will benefit

• Facilities conducting panel retrofits or equipment upgrades that demand a 350A, 2-pole, 600V breaker.
• Maintenance teams replacing failed or worn-out protective devices in Square D installations.
• Engineers specifying exact, compatible parts for legacy systems that rely on the MHP26350 family.

Important compatibility notes

Before ordering, verify fit and ratings for your specific panel and bus configuration. The part number MHP26350 is the most reliable reference to ensure seamless compatibility and safe operation in your system.

Practical tips for installation and use

• Cross-check the panel model and enclosure specifications to confirm that a 350A, 2-pole device matches your design requirements.
• Ensure conductor sizing and protective coordination align with your system’s amperage and voltage levels.
• Keep a spare MHP26350 on hand for future maintenance needs to minimize downtime during replacement.
