A complete range of moulded case circuit-breakers up to 3200 A.
All the circuit-breakers, both three-pole and four-pole, are available in the fixed version; sizes T4 and T5 in the plug-in version and T4, T5, T6, and T7 also in the withdrawable one.
High breaking capacity in compact dimensions
High values of short circuit breaking capacity are guaranteed at different voltage levels, without compromising overall dimensions.
Flexibility of use
Thermomagnetic and electronic trip units are available for use in AC/DC or in AC only. It is possible to interchange trip units keeping the same breaking part, so that installation can be upgraded with fewer costs.
Advanced protection
A complete range of electronic trip units is suitable for different level of protection, even enhancing selectivity values with Early Fault Detection and Prevention algorithm.
Tmax is a complete range of moulded case circuit breakers, covering applications from 320A up to 3200A Tmax T4, T5 and T6 are the moulded case circuit breakers with the best performance/size ratio on the market. T4 and T5 guarantee a breaking capacity up to 200kA at 415V and 80 kA at 690V. T4, T5 and T6 have the same depth, simplifying their positioning in the switchboard compartments, and a standardized and unified range of accessories. Moreover, they complete the r...
Low voltage molded case circuit breakers from 400A up to 3000A Tmax T5 to Tmax T8 have undergone a severe sequence of test in accordance to UL 489 to obtain UL listing and UL marking. Certification in accordance to UL 489 has been extended to the most common accessories as well.
Keeping ahead of the photovoltaic application trends The SACE Tmax PV range of molded-case circuit-breakers and switch-disconnectors for photovoltaic applications offers an increasingly comprehensive, leading-edge solution that anticipates the market trends.
For Variable Frequency applications ABB has always paid special attention to generation of renewable energy, constantly collaborating alongside the major wind turbine manufacturers, sensing the need ahead of others to protect plants with variable frequency.
For applications up to 1000V DC and 1150V AC Over the past years, there has been an increasing requirement for high service voltage in industrial plants. ABB SACE has always been focusing on high demanding applications, so that customers could find a reliable solution for any application need.
Low-voltage, shockproof circuit breakers A modern ship’s operational ability is fully dependent on its onboard electrical infrastructure. Over the years, the growth in the number of electrically powered subsystems on a typical naval vessel has made this infrastructure ever more complex and extensive, and has led to a steady increase in power requirements.
