LS Molded Case Circuit Breakers (MCCBs) are manufactured by South Korea's LS Electric. Compliant with the IEC 60947-2 standard, they are available in a diverse range of 1-phase and 3-phase models across the Metasol and Susol series. The products are highly renowned for their high mechanical durability and ultimate system protection against overloads and short circuits.
In the Vietnamese market, LS molded case circuit breakers are widely popular through two main product series:
- Metasol MCCB Series (ABN, ABS): An economic and standard segment featuring breaking capacities from 14kA to 37kA, specifically engineered for distribution boards in buildings and manufacturing workshops.
- Susol MCCB Series (TD, TS): A premium, high-performance segment boasting breaking capacities up to 150kA and integrated with advanced arc-extinguishing technology, designed for systems requiring ultra-high fault interrupting capabilities.
LS MCCB ranges are available in 2P, 3P, and 4P configurations, with rated currents spanning from 15A up to 1,600A.
LS MCCBs have achieved stringent international certifications including IEC 60947-2, KEMA, CE, and UL. In Vietnam, LS MCCB holds a dominant market share thanks to its excellent heat-resistant Bakelite molded case, stable operation in harsh industrial environments, and a mechanical switching lifespan reaching tens of thousands of cycles.
