ABB Tmax XT circuit breakers include energy monitoringABB is extending its range of moulded case circuit breakers (MCCBs) for the UK with the new SACE Tmax XT that offers higher performances, protection, energy metering and connectivity features up to 1600A.

These new products have been designed with the aim to provide tangible values throughout the customer’s entire journey, from selection and installation to daily use and diagnostics. Superior breaking capacity behaviour and the finest protection that have always characterised ABB’s MCCBs are now combined with the most precise metering and connectivity functionalities, to provide to designers, installers and end-users exclusive options for their daily needs.

SACE Tmax XT breakers set new standards for extreme breaking capacity for heavy-duty applications. The devices are designed to work far beyond the normal constraints, maximising the capacity of installations, regardless of the operating voltage and environmental conditions.

Giampiero Frisio, head of ABB’s Smart Power business says: “Suitable for applications from 160A up to 1600A, the SACE Tmax XT range provides extreme breaking capacity for all voltages and applications. Combined with the world’s most precise electronic trip units in the smallest frames, the new range protects plant investments and ensures continuity of service. With the new Tmax XT series, ABB continues to evolve its offering, building on the success of the innovative Emax 2, the industry’s first smart air circuit breaker.”

SACE Tmax XT sets new standards for plant and energy management. The XT family’s built-in connectivity links smartphones, tablets and PCs to data analysis tools on the ABB Ability cloud platform in real time. The extreme precision of the data measured means users have access to accurate information anywhere and anytime, making it easier to monitor resources and identify savings opportunities. Using the embedded smart power controller can help reduce energy consumption up to 20 per cent.

Niko Railo, global product group manager for ABB’s breakers and enclosures business says: “Upgrading the breakers is also straightforward. As operational requirements evolve, for the first time ever customers can download new functions from the ABB Marketplace, choosing among more than 50 different protection, metering and automation functionalities.”

The same logics, features and intuitive interface are common to all frames, and are also shared with Emax 2 air circuit breakers, making ABB the first company able to provide customers the same logic across the whole circuit breakers portfolio, thus producing significant time savings and enhancing installation quality. Moreover, ABB has streamlined and extended the capability of installation and setting the products: the process is now more user-friendly than ever, and the time needed is reduced by 30 per cent thanks to Bluetooth and Ekip connectivity for mobile devices. Railo continues: “Safety, product quality and reliability under pressure are fundamental to all our products and the Tmax XT series is no different. Customers will immediately recognise ABB’s absolute attention to detail in everything from design to manufacturing.”
