This claw engages the wire form that
runs through the breaker element.
This claw trips the breaker when the
external handle is placed in the open

correctly. Loosing the front brack et
plates will allow some horizontal
adjustment to clear the breaker
element and set the claw properly.
After setting, check clearance by
slowly pushing the breaker element in
position and watch engagement of the
wire form. If clearan ce is ok, rack the
break er into the connect position.

the push button, if the break er trips
free, then the claw must be adjusted to
back o ff the wire form position.
