PURPOSE: An overcurrent trip sensitivity adjusting apparatus for a molded-case circuit breaker is provided to facilitate assembly and improve manufacturing productivity since a support member supports a rotary shaft of a lever or a rotary shaft part of the lever. CONSTITUTION: A bimetal(218a-1) rotates a crossbar(213). A rotatable lever(2) pushes a crossbar with fixed pressure. A sensitivity adjusting spring(3) determines the pressure of the lever and can be replaced. A support member supports the lever to be rotated. The lever comprises an integrated rotary shaft part(2d). |
