Tmax T products family

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.
