APPLICATION NOTES
If required a breathing hole can be made in the cover by removing the nipple.
However be aware that the degree of protection will reduce from IP67 to IP30!

Operation of forcibly guided contacts, Type B
If an outer contact should weld, then the forced operated inner contacts driven by the actuator remain open.
The rotating armature remains free to move.
The unaffected contact pairs can operate normally, i.e. their function to make or break remains unaffected.
The rotating armature remains free to move.
The unaffected contact pairs can operate normally, i.e. their function to make or break remains unaffected.
If an inner contact should weld, then the movement of the rotating armature is blocked via the actuator.
Open contacts of all four contact pairs remain open.
This arrangement corresponds to a conventional forcibly guided contact operation.
Open contacts of all four contact pairs remain open.
