ABB SACE circuit breakers
ABB circuit breakers restore service quickly after a fault while protecting the electrical installation. The range runs from miniature circuit breakers through molded case and air circuit breakers, in standard and high breaking capacity versions, and electronic releases carry that protection into the control and operation of the installation.
ABB SACE molded case circuit breakers come from two families: the established Isomax S series and the Tmax series. Tmax breakers combine high performance with compact dimensions, simple installation and reinforced insulation for operator safety. With their range of protection releases and accessories, they suit distribution and sub-distribution in both AC and DC systems.
Tmax features
- Arc chamber design and fast contact opening limit let-through energy and peak current, reducing heating and electrodynamic stress.
- One common, standardized set of accessories across the range, which keeps spare stock low.
- Residual current releases up to 500 A.
Where they are used
ABB SACE molded case circuit breakers serve industrial and commercial low voltage systems with service currents from 1 to 1000 A: AC and DC distribution switchgear, motor protection in motor control centers, generators, capacitors and final loads.
