Moulded Case Circuit Breakers(MCCB)
The moulded-case circuit-breakers, proposed by ABB SACE, derive from two families of apparatus: the well-known and consolidated Isomax S series and the recent but already much awarded Tmax series.In particular, Tmax are characterised by an extremely high level of 
performances with limited overall dimensions, installation simplicity and an increasingly greater guarantee of safety for the operator thanks to their reinforced insulation. Tmax circuit-breakers, thanks to their performances, completeness of protection releases and accessories, can be used for all distribution and sub-distribution application for both AC and DC electrical plants.
Field of application:
The moulded-case circuit-breakers are used in industrial and civil low voltage plants with service currents from 1 to 1000 A. They are used in direct and alternating current distribution switchgear, for motor protection (Motor Control Center), generators, capacitors and for end users.
