The Eaton Industries MCCB motor protection switch is a compact device with dimensions 140x166x275mm, designed for permanent inset use. It has a nominal continuous current Iu of 500A, connecting the main current circuit through a screw connection. The device uses magnetic switch-off technology and ensures protection with an IP rating of IP20. Its operating voltage is 690V. This switch is highly versatile, covering all applications in just four compact sizes, making it suitable for the IEC market. It features a magnetic short-circuit release in conjunction with an overload relay, and a short-circuit release without overload trip. The switch fulfills all requirements of the AC-3 switching category.
