UBIF240NB | Circuit Breaker | 40A | 2-Pole | 240V

UBIF240NB is an industrial-grade circuit breaker engineered for reliable protection of 240V circuits. With a 40A rating across 2 poles, this device is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter and downtime needs to be minimized.

Key benefits

• Precise compatibility — use the UBIF240NB part number as the definitive reference to match your panel and feeder configurations, reducing guesswork during replacements.
• Two-pole protection — disconnects both live conductors in a 240V circuit, enhancing safety and ensuring coordinated shutoff for motor loads, pumps, and HVAC equipment.
• 40A protection — calibrated to guard moderate-to-high current loads against overloads and short circuits without nuisance trips in normal operation.
• Reliable replacement option — designed to slot into existing installations that require the UBIF240NB’s specific form factor and electrical ratings, helping preserve panel layout and wiring harness compatibility.

Ideal applications

• Maintenance and retrofits on legacy 240V circuits where accurate match is essential
• Replacement for failed or obsolete breakers in industrial control panels
• New installations that demand a 40A, 2-pole 240V protection device with a known compatibility reference

Installation and compatibility tips

• Always confirm fit and ratings before ordering to ensure the breaker exactly matches your panel’s requirements.
• Use the part number UBIF240NB as the best reference to verify compatibility with your enclosure, bus bar arrangement, and accessory options.
• Inspect the panel’s 2-pole 240V circuit layout and ensure safe clearance for installation and future maintenance.

Why choose this model? When your project hinges on a precise specification match, generic substitutes can force extra parts, wiring changes, or panel modifications. The UBIF240NB delivers a controlled, reliable solution designed to integrate seamlessly with compatible systems, deliver consistent protection, and minimize upgrade friction across maintenance, retrofit, and replacement workflows.
