Manual AH Breakers
-
All breakers, manual and electrical, are equipped with a
mechanical TRIP button located on the breaker escutcheon.
Manual opening is accomplished by displacing a mecha­
nism latch that allows the toggle linkage, which holds
the breaker's moveable contacts in the closed position,
to collapse.

AKR-30, -50 AKRT-50
This circuit breaker has a closing spring which is charged by
a number of handle strokes (from one to four) depending on
the angle through which the handle is rotated. U pon comple­
tion of the charging action, the springs are "propped" in the
fully charged position and are discharged only by removing
the "prop," releasing the spring to close the breaker. Closing
is initiated by depressing a mechanical close button on the
escutcheon.

This circuit breaker is closed by first rotating the handle
counterclockwise approximately 1 00 degrees; this resets the
mechanism and partially charges the closing spring. Return­
ing the handle clockwise to the normal position completes
the spring charging and drives the toggle mechanism over­
center, closing the contacts.

Stored Energy Closing
and
AKR-75 -100
This circuit breaker requires four handle strokes to charge
the springs. Un like the smaller AKR frame sizes, the break­
er's contacts close during the fourth handle stroke. Initiation
of closing by separate close button is not available.
