Miniature circuit breaker interlocking mechanism

WNHS Universal Interlock Attachment
Circuit breaker universal interlock accessory (hereinafter referred to as universal interlock), consisting of two-stage (multi-stage) circuit breakers and universal interlock assemblies, is mainly used in home life, business clubs, hotels, shopping malls and other occasions where two main circuits cannot work simultaneously.
The universal interlock, as a separate accessory, is assembled in the middle of a two-stage (multi-stage) circuit breaker. When it is necessary to switch lines, simply disconnect the current power circuit breaker, manually operate the locking screw sliding slider to drag the slider to the current power supply, and then close the power supply that needs to be switched to ensure that the two lines do not conduct at the same time, and switch the power supply safely at any time, playing a role in protecting the normal operation of the power supply line and electrical equipment or other electromechanical equipment.
