MCCB molded case circuit breaker automatic opening distance, overtravel detection equipment

Short Description:

MCCB molded case circuit breakers do not usually have automatic opening distance and overtravel detection, but some models of advanced MCCBs may have some additional features. The automatic opening distance feature refers to the ability of a circuit breaker to automatically break a circuit under certain conditions to protect electrical equipment. This feature is commonly found in distance protection relays or line protection devices, not in the MCCB itself. The over-travel detection function is used to monitor whether the voltage or other parameters of a circuit exceed a set range. This function usually requires the use of an additional device, such as a monitoring device or relay, rather than the MCCB itself. Overall, if you need automatic open-range and over-travel detection functions, it is recommended that you contact a professional electrical engineer to select the appropriate equipment and program for your specific needs.
