The Eaton Industries MCCB motor protection circuit breaker measures 90x88x145mm and has an overload protection setting range of 80 – 100A. It is designed for built-in fixed installations and has a nominal continuous current rating of 100A. The main circuit connection method is unspecified, while the cut-off technology is thermomagnetic. It has an IP20 degree of protection. This breaker is suitable for IEC markets, featuring a modular design for flexible mounting. It is equipped with thermomagnetic releases for motor protection, phase-failure sensitivity, and a tripping class of 10A. It satisfies all IEC/EN 60947-4-1 and IEC/EN 60947-2 circuit breaker requirements for the AC-3 switching category.
