Switchgear in corrosion-proof design
Application
The criterion of a seawater-proof switch shows which requirements have to be met: the switchgear must be able to work without failures even under corrosive conditions during a long life – in all weathers and waves. The safety sensor HS SI 4 for example meets these requirements without problems as well as the magnetic safety sensor RC SI M30, the position switch ES 13 W and the position switch ES 95 offshore. These switching devices feel fine on offshore platforms as well as in wind power plants, on ships and in submarines.
Salt Mist Test
The saltwater resistance of switchgear is verified by means of a salt test in accordance with IEC/EN 60068-2-52/GL/(cyclic salt mist test). According to the requirements of »Germanischer Lloyd«, specimens are sprayed in four cycles of two hours each and then stored at a temperature of +40 °C for seven days. Switching devices developed for offshore applications – e. g. position switches in series ES 95 have to pass these tests.
