CM2,CM2Z series molded case circuit breakerDetailed product description：Column tabs
The CM2 series and CM2Z series plastic shell circuit breakers (hereinafter referred to as circuit breakers) are new types of circuit breakers developed by our company using international advanced design technology and in accordance with the requirements of the IEC60947-2 international new standard. Its rated insulation voltage is 800V, suitable for infrequent conversion in circuits with AC 50Hz/60Hz, rated working voltage of 400V and below, and rated current up to 630A. Circuit breakers have overload, short circuit, and undervoltage protection functions, which can protect circuits and power equipment from damage.

CM2 and CM2Z series molded case circuit breakers are classified into three types based on their short-circuit breaking capacity: L-type (standard type), M-type (higher breaking type), and H-type (high breaking type).
It can be installed vertically or horizontally.
Cannot be reversed into the line, that is, only 1, 3, and 5 can be connected to the power line, and 2, 4, and 6 can be connected to the load line.
It has isolation function, and its corresponding symbol is:.

CM2 and CM2Z series molded case circuit breakers comply with IEC60947-2 and GB14048.2 standards.
Obtained the national mandatory product certification "CCC" mark.
