PROBLEM TO BE SOLVED: To provide an excess current tripping arrangement prepared in the inside of a case of a circuit breaker unit, wherein the excess current tripping arrangement includes two or more bimetals which are formed from a long plate with one end fixed and the other end not fixed and a suspending strip which is pressure-driven by curving the bimetals, and the bimetals prepared for each pole are moved in an interlocking manner by an interlocking member. SOLUTION: The excess current tripping arrangement prepared in the inside of a case of a circuit breaker unit includes: two or more bimetals which are formed from a long plate with one end fixed and the other end not fixed; and a suspending strip which is pressure-driven by curving the bimetals. The bimetals prepared for each pole are moved in an interlocking manner by an interlocking member. COPYRIGHT: (C)2010,JPO&INPIT
