SACE Timeline

Origins and evolution of low voltage air circuit-breakers.

Innovation and a propensity for improvement have, since the very beginning, been characteristic features of SACE.

The history of the company can be understood through the evolution of its main products.
The history of air circuit-breakers officially begins in 1949 with the designing of the DM series. In 1956 a phase of renewal of low voltage devices and also in the field of air circuit-breakers begins, and new devices are developed. From 1960, the year in which production officially starts of Otomax, the first air circuit-breaker in SACE history completely designed and built in Italy, SACE begins following a path marked by the launch on the market of increasingly technologically advanced ranges.

Otomax

Otomax is the first air circuit-breaker to officially enter production in SACE history.
With 2 frame sizes (P2C and P3C), covering models from 1000A to 5000A, it guarantees high performance both in alternating current (up to 660Vac) and in direct current (up to 500Vdc).

Novomax G30

Novomax G30 makes its appearance on the market in 1971 and is presented as the most compact air circuit-breaker of the era. It is introduced ahead of the Novomax series, which arrives eight years later and is its natural evolution.

Novomax

The advantages of the new family are its compact dimensions and high performance. It is provided with sliding contacts for auxiliary circuits, safety shutters on the fixed part and enables a mechanical interlock to be constructed between the two circuit-breakers.

The new series is launched in 1989, a year after the establishment of ABB as a major international electrotechnical Group. In 1988 SACE, in fact, following the merger of the Swedish company Asea with the Swiss Brown Boveri, becomes ABB SACE.

New Emax

It is characterized by an increase in electrotechnical performance, with an increase in maximum interrupting voltage to 1.150Vac, thanks to the presence of a new range of electronic trip units (PR121-PR122-PR123 series) and innovative current sensors.

New Emax X1

The small great air circuit-breaker of the Emax family. With models from 630A to 1,600A, it guarantees the performance of an air circuit-breaker but with the dimensions of a mouldedcase circuit-breaker.
