TOMC7-63 DC 1P MCB from TONGOU is used in direct current circuits (Industrial control and automations, transport, renewable energy). It  combine the following functions of circuit protection against short-circuit and overload currents, control and isolation. It is C curve,whic can provide overcurrent protection for any type of application. The green strip indicates that all the poles are open and allows work to be carried out on the downstream circuit in complete safety.
