NM032250 | Circuit Breaker | 250A | 3-Pole | 240V

The NM032250 circuit breaker is an industrial-grade protective device designed for 3-phase 240V power distribution. With a robust 250A rating and a 3-Pole configuration, it delivers reliable overcurrent protection for demanding maintenance, retrofit, and replacement projects where exact specifications matter.

What makes this circuit breaker essential

• Precise 250A protection bluntly guards feeders and motors against overloads, helping prevent equipment damage and unplanned downtime.
• Three-pole design ensures balanced protection across all three phases (A, B, and C), keeping your 3-phase system stable during fault events.
• 240V operating rating aligns with common industrial distribution networks, making it a straightforward drop-in for compatible panels.
• Part number NM032250 serves as the most reliable reference for compatibility, reducing guesswork during procurement.
• Versatile for service work ideal for routine maintenance, panel retrofits, or replacements where exact spec matching is required.

Ideal use cases

• Replacing a failed or outdated 3-pole 240V breaker in an industrial control panel or power distribution board.
• Retrofitting existing systems to restore original protection in 3-phase circuits that demand 250A capacity.
• Standardizing protective devices across multiple machines or lines to maintain consistent trip characteristics and safety.

Fitment and selection tips

• Verify fit and ratings before ordering. Use the NM032250 as the primary compatibility reference to ensure correct mounting, trip characteristics, and enclosure fit.
• Match the amperage and pole count to your panel’s design and the connected loads to prevent nuisance trips or under-protection.
• Check panel documentation for any model-specific mounting or accessory requirements to ensure a seamless installation.

Practical considerations for installation and maintenance

When installing, ensure the power is isolated and follow the panel manufacturer’s wiring guidance. Keep a record of the part number NM032250 for future replacements to maintain consistent protection. For ongoing reliability, store spare units in appropriate conditions and replace only with identical specifications to preserve intended electrical performance.
