4.9.8 Door-coupling rotary operating mechanism
4.9.8.1 Description
Door-coupling rotary operating mechanism
Motor starter protectors with a rotary operating mechanism can be installed in the control
cabinet and operated externally by means of a door-coupling rotary operating mechanism.
The mechanism engages when the control cabinet door closes. If the motor starter protector
is active, the coupling locks, thereby preventing the door opening unintentionally. This lock
can be deactivated by maintenance personnel. In the OFF setting, the rotary operating
mechanism can be secured against reclosing with up to 3 padlocks. The padlocks prevent
the door from opening unintentionally.
Door-coupling rotary operating mechanisms
The door-coupling rotary operating mechanisms comprise a knob, a coupling driver, and an
extension shaft 130/330 mm in length (6 x 6). They are dimensioned for IP65 degree of
protection. The interlocking of the door prevents the unintentional opening of the control
cabinet door when the switch is set to ON. The OFF setting can be locked with up to 3
padlocks.
Door-coupling rotary operating mechanism for arduous conditions
The door-coupling rotary operating mechanisms comprise a knob, a coupling driver, and an
extension shaft 300 mm in length (8 x 8 mm), a spacer and two metal brackets, which are
used to mount the motor starter protector.
The door-coupling rotary operating mechanisms are dimensioned for IP65 degree of
protection. The interlocking of the door reliably prevents the unintentional opening of the
control cabinet door when the switch is set to ON. The OFF setting can be locked with up
to 3 padlocks.
Laterally mountable auxiliary releases and 2-pole auxiliary switches can be used. The door-
coupling rotary operating mechanisms meet the requirements for isolating function according
to IEC 60947-2.
