ABSTRACT:
An automatic electric side-by-side two-pole circuit breaker having an insulating casing formed from the complementary association of a base casing, an intermediate casing and a cover which provide a pair of mechanism receiving compartments in side-by-side association. Each compartment carries a pivotally supported operating handle which extends partially outward from the casing for external manual operation, a line terminal, a load terminal electrically connected to said line terminal, a stationary contact intermediate said line terminal and said load terminal and a movable blade which carries a movable contact on one end and has its opposite end connected to the handle. A releasably latched generally thin trip lever is pivotally mounted within the compartment and is releasable from its latched position to a tripped position to effect separation of the contacts. The trip lever includes an upstanding leg which is engaged by a protuberance on the handle for resetting the trip lever. The handle overlaps the trip lever as does the movable contact blade which has an extending top segment received in a recess of the handle for operation of the movable blade by the handle. A spring is connected between the generally J-shaped blade and the trip lever for snap action of the blade.
