ABB T2S040TW 40A 3-Pole 480 V Circuit Breaker Potential Transformer

The ABB T2S040TW is a rugged, three-pole circuit breaker designed for demanding 480 V three‑phase environments. With a 40 A current rating, it delivers precise protection for motors, pumps, and other critical loads while simplifying panel wiring and maintenance. Built for reliable interruption and safe shutdown, this device integrates smoothly into modern power distribution networks and is compatible with protection and metering schemes that rely on potential-transformer based monitoring.

What sets this ABB model apart?

• Three-pole protection for balanced shutdown. Disconnects all three phases simultaneously to prevent neutral faults and phase imbalances during faults.
• 40 A per‑phase protection. Adequate for moderate-load circuits, ensuring protection without unnecessary nuisance trips in variable-speed drives, conveyors, or HVAC systems.
• 480 V operational rating. Ready for standard industrial power networks, switchgear, and panel boards used in manufacturing, warehousing, and data centers.
• Robust ABB engineering. Trusted protection performance and compatibility with contemporary protection schemes, supporting long-term reliability and maintenance ease.
• Compact, installation-friendly design. Fits common control panels and MCCs with clear labeling to facilitate quick replacement and servicing.

Ideal applications include protecting three‑phase motors in conveyors and fans, safeguarding pumps in water treatment or HVAC systems, and serving as a dependable main or feeder breaker within switchgear assemblies. If you’re upgrading from smaller breakers, the T2S040TW provides a focused, reliable level of protection matched to 480 V systems without over-specifying.

Practical tips for deployment:

• Use with compatible ABB components in 480 V networks to maintain coordinated protection across your distribution scheme.
• Leverage potential-transformer compatible protection and metering where monitoring and fault-detection rely on reduced-voltage signals.
• Verify panel compatibility and mounting orientation to ensure reliable operation and straightforward future maintenance.

Equip your electrical distribution with the ABB T2S040TW—a dependable, 40 A, 3‑pole, 480 V circuit breaker that delivers precise protection and straightforward integration for demanding industrial environments.
