Contact load:
70 W
Type of protection:
IP 65 in inserted and
secured status
Contact:
normally open/closed
Cable connection:

The switching function can be changed by turning the electric upper
part by 180° (normally closed contact or normally open contact). The
state on delivery is a normally closed contact. By inductivity in the
direct current circuit the use of suitable protection circuit should be
considered. Further maintenance indicator details and designs are
available in the maintenance indicator data sheet.

We draw attention to the fact that all values indicated are average
values which do not always occur in specific cases of application.
Our products are continually being further developed. Values, di-
mensions and weights can change as a result of this. Our special-
ized department will be pleased to offer you advice.

We recommend to contact us concerning applications of our filters in
areas governed by the EU Directive 94/9 EC (ATEX 95). The stand-
ard version can be used for liquids based on mineral oil (correspond-
ing to the fluids in Goup 2 of Directive 97/23 EC Article 9). If you
consider to use other fluids please contact us for additional support.
