More about selecting SIRIUS ACT 3SU parts
Use of SIRIUS ACT 3SU parts
SIEMENS SIRIUS ACT 3SU control elements are used to control machines and switchboards. The range includes mushroom-head switches, emergency stop buttons and potentiometers.
Part selection and replacement
SIRIUS ACT control elements are used on machine control panels and switchboards. When selecting them, compare the mounting dimensions, the function of the head and the required contact or signalling modules. For mushroom pushbutton heads, check the locking mechanism and the method of release. A backlit version does not automatically include a lighting module. For lockable versions, check the lock number and details regarding the supply of a key. The emergency stop safety function requires appropriate complete wiring.
