CNKA molded case circuit breaker dc mccb Feature


1.  The operating mechanism features quick closing and quick breaking functions.

2.  In the contact arc extinguishing system, the dynamic and static contacts utilize the principle of parallel conductors. The static contacts are H-shaped and designed to repel, enabling rapid breaking under high current. Components made from high arc-resistant materials are installed around the dynamic and static contacts to facilitate rapid arc extinguishing.

3.  The structure is compact and the volume is small.

4.  Various models, including thermal magnetic, leakage current, DC, and intelligent types, share unified overall dimensions.

5.  Accessories can be independently installed, allowing users to easily open the accessory cover to install or replace them.

6.  Mechanical and electrical interlocking can be installed between two circuit breakers.

7.  The operation is safe and reliable with zero or short flashover.

8.  Easy to use, allowing for on-site installation by users.
