CHOSO COM1 Series Molded Case Circuit Breakers (MCCB)

The CHOSO COM1 Series Molded Case Circuit Breakers (MCCB) provide reliable protection for safe power system operation across industrial, commercial, and residential applications. Available in multiple ampere ratings from 100A to 1250A (including 100A, 250A, 400A, 630A, 800A, and 1250A) and offered in both 3-pole and 4-pole configurations, these breakers can be flexibly configured to match diverse electrical system requirements.

Engineered with high-performance short-circuit breaking capacities—featuring Icu ratings up to 65kA and Ics up to 45kA—and fully compliant with IEC/GB standards as well as CCC certification, the COM1 series ensures consistent and dependable protection under demanding conditions. The insulating enclosure, clearly visible status indicators, and modular construction further enhance operational safety, user visibility, and maintenance convenience. Equipped with integrated overload and short-circuit protection, these MCCBs effectively limit fault-induced damage while maintaining system continuity and stability.
