CM2L series plastic case circuit breaker with residual current protectionDetailed product description：

The CM2L series plastic shell circuit breaker with residual current protection (hereinafter referred to as the circuit breaker) is one of the new circuit breakers developed by our company using international advanced design technology and in accordance with the requirements of IEC60947-2 international 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, as well as residual current display, alarm, protection, and communication functions. They can also be used as residual current fire monitors.

The CM2L series plastic case circuit breaker with residual current protection can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally);
Do not reverse the line, that is, only allow 1, 3, and 5 to be connected to the power line, and 2, 4, and 6 to be connected to the load line;
It has isolation function, and its corresponding symbol is:;
Compliant with IEC60947-2 and GB14048.2 standards;
Obtained the national mandatory product certification "CCC" mark.
