    Re: Operation of MCB shunt tripping module

    You don't need to disassemble it to know how it works.

    Some MCB series have a mechanical interface for auxiliary modules, either signal contacts or external actuators. Shunt tripping module is just a solenoid coil driving this interface.

    Depending on the MCB series, the interface is either through a lateral opening or to MCB handle. Review MCB catalogs and datasheets for details.
