ICHYTI molded case circuit breaker dc mccb Feature
◉ The operating mechanism has quick closing and quick breaking functions.
◉ In the contact arc extinguishing system, the dynamic and static contacts are installed using the principle of parallel conductors. The static contacts are designed in an H-shape and can be repelled, which is conducive to rapid breaking under high current. Components made of high arc resistant materials are installed around the dynamic and static contacts, which is conducive to rapid arc extinguishing.
◉ Compact structure and small volume.
◉ Various models such as thermal magnetic, leakage current, DC, and intelligent have unified overall dimensions.
◉ Accessory independent installation unit, users only need to open the accessory cover to install and replace accessories.
◉ Mechanical and electrical interlocking can be installed between two circuit breakers.
◉ Zero or short flashover, safe and reliable operation.
◉ Easy to use, users can install on site.
