Connection designation according to EN 50013
The switching point of snap-action contacts remains constant throughout the
whole service life independent of contact erosion.
Current carrying capacity AC15 / DC13
Exchanging the actuator head
The part-turn actuator is pre-stressed and must be held in position!
Unscrew enclosure cover (
1
), turn locking plate (
2
) to the right, pull off actuator
head (
3
).
Insert new actuator head (
3
) as far as it goes, turn locking plate (
2
) to the left,
screw on enclosure cover (
1
).
Part-turn actuator 3SE5000-0AH00
(left or right-hand switching)
Setting the actuator head for either left or right-hand switching (at the fac-
tory)
Actuator plunger (
4
) turned to the left by 90° = left-hand switching.
Actuator plunger (
4
) turned to the right by 90° = right-hand switching.
