Technical data
CE marking
SUCO pressure switches rated
with an operating limit of 250 V
are covered by the Low Voltage
Directive 73/23/EC.
An EC Declaration of Confor-
mity has been issued for these
pressure switches and is on file
at our offices. The correspon-
ding switches bear the CE mark
in our catalogue.
Degree of protection IPXX
The type approval does not
apply without restriction to all
environmental conditions.
It is the responsibility of the
user to check whether the
electrical connection complies
with regulations other than
those stated and whether it can
be used for special applications
which could not be foreseen by
us.
Oxygen warning!
When using oxygen, the
relevant safety regulations
must be observed. In addition,
we recommend that a maxi-
mum operating pressure of 10
bar (50 bar for stainless steel
enclosures) must not to be
exceeded.
