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
Flexibility of use
Advanced protection
-
High values of short circuit breaking capacity are guaranteed at different voltage levels, without compromising overall dimensions.
-
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.
-
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.
