Scope application

Dual power interlock conversion accessory (hereinafter referred to as interlock conversion accessory), composed of two-stage (multi-stage) circuit breakers and interlock conversion accessories assembled, is mainly used in home life, business clubs, hotels, shopping malls and other occasions where two main circuits cannot work simultaneously. The interlocking mechanism, as a separate mechanism, is assembled between two (multi-stage) circuit breakers. When the commonly used power circuit breaker is conducting and needs to switch lines, simply manually operate the handle of the backup power circuit breaker to close it. Before the backup power circuit breaker is conducting, the commonly used power circuit breaker will automatically and quickly disconnect under the interlocking conversion accessory to ensure that the two lines will not conduct at the same time, and the power supply can be safely switched at any time, playing a role in protecting the normal operation of the power circuit and electrical equipment or other electromechanical equipment. Regardless of the primary or secondary, both circuit breakers can achieve the above operations.
