1-0 DESCRIPTION
The Allen-Bradley general purpose rotary handle
mechanism is suitable for use with NEMA 1, 3R, 12 and
4, 4x fabricated enclosures. For NEMA 4 and 4x enclo-
sures the rotary handle is labeled and gasketed for these
applications. It is designed for use with
Q-Frame and M-Frame Circuit Breakers, Molded Case
Switches and HMCP’s up to 800 amps (Figure 1-1).
Required for a standard application are the operating
handle, shaft, and mechanism.
The rotary handle mechanism is Underwriters
Laboratories, Inc. listed for field installation.
The operating handle has been designed to meet NFPA
79 requirements. It may be mounted in either the horizon-
tal or vertical direction. The handle was ergonomically
designed with extra clearance for a "gloved hand" to

operate. It may be padlocked in the OFF position utilizing
3 padlocks (.312 Max).
The standard label in the operating handle indicates ON/
Tripped/OFF/Open/Reset. To fulfill international require-
ments, an alternate handle may be ordered which indi-
cates (1)/Tripped/(O)/Open/Reset.
To meet the various enclosure depths, four variable depth
shafts are offered (6", 12", 16", and 24"). Each shaft
includes a support brace to ensure proper alignment. In
addition, the 16" and 24" extra long shafts include an
adjustable support bracket.
The standard mechanism located on the breaker does
include means for internally locking the breaker in the
"OFF" position with up to 3 padlocks each with a maxi-
mum diameter of .312".
As an option, an auxiliary switch is offered so that the
control panel builder may electrically indicate the status of
the breaker. This accessory would be mounted on the
mechanism and comes with 24" pigtail leads.
