摘要
A trip device comprises a first transmission bar pivoting around the same pivoting axis as a ratchet by any one of several thermal actuators. The first transmission bar drives the ratchet from a latched position to a released position, and makes a first indicator change state. A second transmission bar can be pivoted around the same pivoting axis as the ratchet by any one of several magnetic actuators. This second transmission bar drives the ratchet from its latched position to its released position, and makes a second indicator change state.
