More Information
Summary:The invention discloses a circuit breaker, which can prevent clapboard from breaking resulted from overpressure inside the circuit breaker, and can separate the breaking part with fixed contact, movable contact and explosion chamber from clapboard for loading side with switching mechanism and overcurrent trip. The breaking part with fixed contact(3), movable contact (5) and supporting rack (9) andexplosion chamber (6) are accepted in the out shell (1), and the stripping mechanism with trip rod (17) and switching machanism (4) are accepted in middle cover (2). The the breaking part with fixedcontact, movable contact and explosion chamber is separated from clapboard for loading side with switching mechanism and overcurrent trip by joint plate with conductivity such as metal joint plate (14).
