Description
Air circuit breaker series launched in 1971, was available in different versions and is now obsolete
Circuit Breakers Low Voltage ABB – SACE Novomax was presented as the most compact air circuit breaker of the era. Solid and reliable, thanks to the availability of a range consisting of six frames (G30-G2-G3-G4-G5-G6), covered uniterrupted breaking capacity Iu up to 6300A models and guaranteed breaking capacity Icu up to 100kA at 660V AC. The range included T series thermal relays and could be equipped with S1 and S2 series electronic relays.
Moreover, G protection for earth faults and logic output signals (S2 series) was introduced.

Novomax G30 (1971)
Circuit Breakers Low Voltage ABB – SACE Novomax G30 makes its appearance on the market in 1971 and is presented as the most compact air Circuit-breaker of the era. Solid and reliable, it covers frame sizes from 800A to 1600A. It is introduced ahead of the Novomax series, which arrives eight years later and is its natural evolution.
Novomax (1979)
The evolution of SACE air circuit-breakers continues with a focus on compactness and optimization of performance. Novomax, continuing the path begun with the Novomax G30 series, ensures continuity and, at the same time, innovation.
The advantages of the new family, launched in 1979, are its compact dimensions and high performance. Novomax, thanks to the availability of a range consisting of 5 frame sizes (G2-G3-G4-G5-G6), covering up to 6300A models, guarantees performance of up to 100kA at 660Vac. 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 range includes T series thermal relays.
It is equipped with S1 and S2 series electronic relays. G protection for earth faults and logic output signals (S2 series) are introduced and electromagnetic compatibility (S2/MM series) is implemented.
