Options (factory options)

Gasket: FPM or EPDM
Contact: Change over contact or ATEX certified contact

The switch is SPST type, NO / no flow. Reversing the contact, it is possible to have the NC action.
The adjustment is continuous, sliding the switch on a guide and fixed it up with a screw.
The output connection is realized through an IP 65 connector DIN 43650, PG 9.

Standard switch:
NO contact, switching power 230 V / 1 A / 50 VA

Change over contact:
On request, switching power 250 V / 1.5 A / 50 VA
