SACE Emax circuit breaker series consisted in five sizes (E1, E2, E3, E4, E6) available in fixed and withdrawable version with rated uninterrupted currents Iu from 800 to 6300A and breaking capacities Icu up to 150kA at 440V AC, 100kA at 690V AC and 65kA at 1000V AC.
From an architecture point of view, the design was developed using the concepts of modularity. Electronics played a crucial role thanks to the PR111/PR112/PR113 series of electronic trip units with liquid crystal displays that permitted also a harmonic analysis of the currents.
To complete the offer a new series of selective circuit breakers (L range) current limiting was introduced.
Emax was the first series of ABB SACE air circuit breakers with the UL mark.
