Low Voltage Circuit Breakers
ABB low-voltage circuit breakers are power protection solutions designed with digitalization, energy efficiency, and infrastructure reliability in mind.
Advanced circuit breakers such as SACE Emax 3, Emax 2, and Tmax XT provide predictive maintenance, arc-flash protection, and enhanced cyber security features.
ABB offers a complete product portfolio including molded case circuit breakers (MCCB) and air circuit breakers (ACB) ranging from 160 A up to 6,300 A.
With scalable Ekip architecture and digital connectivity, ABB solutions enable optimized power management across a wide range of industries and critical infrastructure.
Medium Voltage Circuit Breakers
ABB medium-voltage vacuum circuit breakers safely interrupt power flow during power system faults and enable rapid system recovery.
They protect electrical networks from various faults such as overcurrent, lightning strikes, equipment failures, and short circuits, serving as key components in medium-voltage switchgear for reliable and continuous power supply.
The widely used VD4 vacuum circuit breaker supports up to 36 kV rated voltage, up to 4,000 A rated current, and up to 50 kA breaking capacity, making it suitable for a wide range of medium-voltage distribution environments.
Based on more than 20 years of proven technology and experience, ABB circuit breakers are widely used in OEM applications, panel builders, EPC projects, and electrical system retrofit or upgrade projects.
