Door mounted rotary operator

With the door mounted rotary operator installed, it is possible to operate the molded case circuit breaker through the control cubicle door without opening the door.

Door interlock with door mounted rotary operator

The door interlock of the door mounted rotary operator locks the door as soon as the door mounted rotary operator is turned to position ON (I).

Overriding the door interlock

The door interlock can be overridden by a deliberate action. This means that the door can be opened with the operator in position ON (I) so that maintenance can be carried out, for example. It is also possible to disable the door interlock completely. For details, see the Operating Instructions https://support.industry.siemens.com/cs/attachments/27014447/A5E01223757_04exp_201305291320122231.pdf

  1. Turn the door mounted rotary operator to the OFF (O) position.

  2. Open the cubicle door.

  3. Use a tool to turn the shaft to the ON (I) position in order to close the molded case circuit breaker.
    Alternatively, the supplementary handle for the door mounted rotary operator can also be used to close the breaker.

  4. Press the button <PUSH TO TRIP> with a tool such as a screwdriver.
    The door mounted rotary operator moves from position ON (I) to position TRIP. The molded case circuit breaker is now in the tripped state.

  5. Turn the door mounted rotary operator counter-clockwise to the limit stop (RESET position, just beyond OFF (O)).
    The manual operator remains in the OFF (O) position.

  6. Close the cubicle door.
    The molded case circuit breaker can now be closed again.

  2. Turn the supplementary handle to the ON (I) position in order to close the molded case circuit breaker.

Variable depth adapter

The variable depth adapter can be installed to compensate the distance traveled between the TEST and DISCON positions with draw-out units. With this device installed, the cubicle door need not be opened when the breaker is in the TEST or DISCON position. See also chapter Draw-out technology
