Circuit Breakers

ABB offers the best solution for restoring the service condition rapidly in case of fault, providing at the same time optimum protection of the electrical installation. From the miniature circuit-breakers to the moulded-case and air circuit-breakers of the standard and high-breaking capacity type, with the ABB range, every technical problem has been solved. A reliable and advanced reply which, thanks to the interaction of electronics, is also present today in the control and operation stages of electrical installations.

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 (Top selection at Intel Design 2003 for their technological content and respect of the environment ). 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.

Specific characteristics of Tmax
The Tmax series is characterised by being a product with a high technological content - the fruit of the most advanced design and simulation tools with excellent performances in minimum overall dimensions.

Thanks to the new technology used for the arcing chambers and the speed of contact opening, the circuit-breakers of the Tmax series guarantee strong limitation of the specific let-through energy and reduction in the peak currents, therefore limiting overheating of the devices and electro-dynamic stresses.

Furthermore, the new Tmax circuit-breakers use a completely common and standardised range of accessories with considerable advantages in terms of reduced stocks as well as flexibility and ease of use. Then within this range there are also the new residual current releases up to 500 A.

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.
