Air Circuit Breakers (ACB)

AIR CIRCUIT BREAKERS

Seamless Integration
Emax 3 offers backward compatibility with Emax 2: no redesign or retesting is needed for your
system. Compared to Emax 2, the ABB SACE Emax 3 breaker offers: 1
• The same dimensions and mounting points
• The same minimum enclosure requirements
• The same power and auxiliary connection
• Compatibility between the Emax 2 fixed part and the Emax 3 moving part

Adaptive microgrid protection
Under diverse plant conditions it is important to ensure high level of selectivity and continuity
of service. Emax 3 can adapt its protection settings to different scenarios by changing
relevant thresholds during transitions:
• Dual setting for most frequent applications
• Triple setting for an additional set of thresholds

MDGF protection
Emax3 guarantees the Modified Differential Ground Fault protection in a new, smart and easy
way, reducing installation time and overall space required in the panel:
• Logic managed via Link internal communication
• No need for additional phase current transformers
• No need for external summing current transformers

RELT protection
Emax 3 improves operator safety during maintenance by Reduced Energy Let-Through
protection management in an easier way with Ekip Aware:
• Color change on trip unit display when protection is enabled, for immediate status vision
• Activation/deactivation also via EPiC mobile app, keeping operator away from
switchboard
