Description

technical field [0001] The invention relates to an electromechanical tripping device suitable for a leakage protector. Background technique [0002] GB20044-2005 (equivalent to IEC61540-1999) and GB16916.1-2003 (equivalent to IEC61008-1996) national and international standards require that the mechanical structure of the leakage protection device should have a free tripping mechanism, the so-called free tripping is the requirement When the switch contacts are in the closing process at any time, it should be ensured that the switch contacts can be broken at any time. [0003] However, the tripping mechanism of the existing product has defects such as complex coordination, many parts, complicated processing and high product cost in electromechanical application. Contents of the invention [0004] An electromechanical tripping device suitable for leakage protector provided by the present invention utilizes various physical characteristics of electromechanical, electric and m...
