Circuit breaker crossbar assembly

A circuit breaker comprising:

• a plurality of moveable contacts configured to conduct current through said circuit breaker;
• a mechanism configured to actuate movement of said plurality of moveable contacts;
• a first bracket located on a first side of said circuit breaker;
• a second bracket located on a second side of said circuit breaker;
• an elongate crossbar comprising a longitudinal axis defining a first end operatively coupled to said first bracket, a second end operatively coupled to said second bracket, and at least one support portion disposed therebetween, said first end and said second end each rotatable between a first rotational position and a second rotational position and operatively coupled to said mechanism and to said plurality of moveable contacts to selectively rotate said plurality of moveable contacts;
• said crossbar further comprising a first stop wall and a second stop wall defining a recess therebetween;
• and
• a support structure disposed in said recess, said support structure having a support end engaged with said crossbar, a first support wall arranged to operably engage said first stop wall upon rotation of said crossbar to said first rotational position, and a second support wall arranged to operably engage said second stop wall upon rotation of said crossbar to said second rotational position.
