Thomas & Betts QCAL-90 Circuit Breaker, 90A, 2-Pole, 240V

Meet the Thomas & Betts QCAL-90 Circuit Breaker — a robust solution designed for industrial electrical service, maintenance, and replacement projects. With a 90 A rating, 2-pole construction, and 240 V operation, it’s engineered to protect demanding circuits in tough environments while simplifying replacements and upgrades.

Why this breaker stands out

• 90 amp capacity in a compact 2-pole package provides reliable overcurrent protection for heavy-duty 240 V circuits.
• Industrial-focused design built to support ongoing service, routine maintenance, and timely replacements within commercial and manufacturing settings.
• Clear compatibility path — verify fit by part number and application requirements to ensure you're selecting the right device for your panel and wiring configuration.
• Trusted manufacturer — Thomas & Betts delivers consistent performance and availability for field service and ongoing projects.

Ideal use scenarios

• Protect 240 V motor feeders and critical branch circuits in manufacturing lines and industrial facilities.
• Replace aging or failing breakers during scheduled maintenance to minimize downtime and keep systems running smoothly.
• In new installations, deploy a 90 A, 2-pole breaker to reliably guard high-demand loads without over-tripping.

Practical guidance for your project

• Compatibility first — use the QCAL-90 part number as the quick reference to confirm fit with your panel model and wiring setup.
• Protection you can rely on — selecting the correct amperage and pole configuration helps prevent overloads and short circuits that could interrupt critical operations.
• Streamlined procurement — a single, consistent part number for ordering reduces guesswork and accelerates project timelines.
