From the outset, T1, T2, and T3 were designed for superior compatibility, with their functions and performance outperforming those of similar-sized circuit breakers. They share a depth of 70mm and are extremely easy to install. Their new arc-quenching chamber, made of gas-producing materials and featuring an innovative structure, significantly reduces arc-quenching time. Additionally, they come with a thermal release with adjustable door limit value and a new three-pole or four-pole residual current release that is easy to assemble with the circuit breaker, optimizing the space in the switchgear cabinet. T1, T2, and T3 come with a set of standard accessories.

T4, T5, and T6 circuit breakers offer superior performance-to-size ratios among their peers, thanks to their comprehensive series, advanced electronic trip units, and a complete set of standard accessories, making them suitable for a wide range of applications. ABB ensures the TMAX series boasts higher performance and a higher rated current-to-volume ratio through the use of high-quality materials and innovative structural technology. At 415V AC, the T4 and T5 have a breaking capacity of up to 200 kA; at 690 VAC, it reaches 80 kA. They are also applicable to 1150 V AC and 1000 V DC. With the latest electronic trip unit technology, ABB can offer more and better technical solutions. The T4, T5, and T6 share the same depth of 103.5mm and uniform standard accessories, ensuring easy installation, convenience in use, and reduced inventory.
The T7 circuit breaker is highly versatile, accommodating both fixed and withdrawable types for both vertical and horizontal installations, and comes with a variety of terminal options. It features a new pull-out system that makes the operation of the moving parts faster and safer. The significantly reduced height of the T7 circuit breaker simplifies cable routing. The T7's most innovative feature is the quick-connection accessory system, with wiring inside the breaker that connects to external circuits quickly, simply, and safely. The T7 circuit breaker can achieve horizontal or vertical mechanical interlocking between two breakers using its unique flexible cables, and it can also be mechanically interlocked with air circuit breakers.
