TLDR
In this paper, a solenoid operated circuit breaker trip device has a base defining a guide channel (38) and an actuator (32) that slides in the guide channel and interacts with a contact breaking mechanism (24) having a trip bar (36) operable to make or break electrical contacts.Abstract:
A solenoid operated circuit breaker trip device has a base defining a guide channel (38) and an actuator (32) that slides in the guide channel and interacts with a contact breaking mechanism (24) having a trip bar (36) operable to make or break electrical contacts. A spring (34) biases the actuator toward the trip bar. A solenoid (28) on the base electromagnetically displaces a plunger (62) along a linear path and is coupled to a trigger (26) having a latching surface (46) that holds or releases the actuator. The guide channel runs parallel to the path of the plunger, adjacent the solenoid. The trigger is L-shaped and pivoted on a pivot pin (52) between two legs (54,56) of its L-shape, on an axis transverse to the path of the plunger. One of the two trigger legs (56) is coupled to the plunger, and the other (54) has an engagement surface that is moved behind a complementary surface (44) of the actuator to selectively block its displacement. The base can be a slotted frame attached to the solenoid or a molded housing having an interior cavity for receiving the solenoid. A return spring (84) urges the trigger toward the latching position.read more
