Check Availability of our Stock ProductsApprovals
Almost all of Bär switches are tested and approved according to EN 61058-1 resp. IEC 61058- 1 and UL 1054.
The corresponding certificates are available on request.
Approval marks, certification marks
ENEC - Mark, the switch fulfils European (EN) Standards. The two digits numbers indicates which certification body has issued the ENEC Certificate.
UL UR-Mark recognized compount mark for the USA.
cULus-Mark for Canada and USA.
CE Mark, administration mark.
The CE Mark is an administrative mark that is often mistaken for a certification mark. This mark indicates conformity of a product with the EC Directives and the manufacturer can affix the mark by themselves. Almost all of Bär switches are in full compliance with these directives.

Explosionsproof IEC60079-15:1987
The switch must withstand an internal explosion without igniting a surrounding gas mixture.
Resistance to tracking
The resistance to tracking (PTI / CTI values) indicates the maximum voltage which a material withstands a definite quantity of drops of test solution without tacking.
Resistance to head and fire
The materials pass the glow-wire test level 3 carried out at 850°C.
