SACE EMAX 2 ML
SACE Emax 2 ML is ABB's low voltage air circuit breaker range, engineered for the rigorous demands of naval electrical installations. With ratings up to 6300 A, it combines advanced protection and precise power control to ensure high availability and continuity of service — keeping critical marine operations running with confidence.
LOW-VOLTAGE SHOCKPROOF CIRCUIT BREAKERS
A modern ship’s operational ability is fully dependent on its onboard electrical infrastructure. Over the years, the growth in the number of electrically powered subsystems on a typical naval vessel has made this infrastructure ever more complex and extensive, and has led to a steady increase in power requirements.
Since the 1950s, ABB has been manufacturing circuit breakers with special features not available on the same series of equipment destined for general use. Based on this long experience, ABB is proud to offer ML series of circuit breakers for naval applications.
