THERMAL-MAGNETIC TRIP DEVICE FOR TRIPPING A MULTIPHASE CIRCUIT BREAKER

摘要

Thermal-magnetic trip device for tripping a multiphase circuit breaker In a trip device, a first transmission bar (31) can be pivoted around the same pivoting axis (Y2-Y2) as a ratchet (30) by any one of several thermal actuators (40), with a movement in the course of which this first transmission bar (31) both drives the ratchet (30) from a latched position to a released position and makes a first indicator (11) change state. A second transmission bar (32) can be pivoted around the same pivoting axis (Y2-Y2) as the ratchet (30) by any one of several magnetic actuators (42), with a movement in the course of which this second transmission bar (32) both drives the ratchet (30) from its latched position to its released position and makes a second indicator (12) change state.
