Trigger mechanism of residual current circuit breaker with overcurrent protection, comprising a shutter control mechanism associated with residual current circuit breaker control the draw bar and trip relay, the controller (1) of residual current circuit breaker trigger mechanism is positioned control spring (9), whereby in the first lever (3) of the shutter is located in the hole (33) of the first launching the second lever end (22) of the control rods, which reaches into the hole (42) of the rotating body mechanism and in the first lever (3) trigger is designed sleeve (34) of the first lever trigger, which is pivotally located on first pillar (41) of the rotary shutter mechanism of the body, and on the other side of the first lever (3) of the trigger is created the first stop (31) and the first trigger lever stop (32) signaling defects of the protected perimeter of the first lever trigger an intermediate in the second pillar (43) of the rotating body with the trigger mechanism housing (55) of the second trigger lever pivotally placed second lever (5) of the shutter, which has created a flexible upper portion (51) of the second trigger lever, which is designed to claw (53) of the second lever and the trigger stop (52) signaling intermediate position lever trigger, while in the middle of the rotary body (4) trigger mechanism is located the second column (43) rotary shutter mechanism of the body, on which a second lever pivotally (5) initiated by a housing (55) of the second lever trigger, while on the other side of the rotary body (4) trigger mechanism is designed arm (44) rotating the body of the trigger mechanism, while on the carrier (12) pins is pivotally positioned rotating body (4), with a trigger mechanism housing (45) of the rotating mechanism of the body first shutter (45) rotatable lever trigger mechanism body. |
