From the developer:
Air circuit breakers can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit breakers of electrical machines (generators, motors, transformers, capacitors).
All the SACE Emax circuit-breakers except for Emax X1, have the same height and depth both in the fixed and withdrawable version and allow construction of compact switchgear.
