New ATEX maintenance switch
suitable for zone 21

In industrial applications like fruit and animal feedingstuffs production inflammable coating powders will occur. These inflammable powders are generating if small and low dense enough in combination with the aerial oxygen an explosive atmosphere. Inflaming this atmosphere will evoke an explosion which can cause serious personal injuries and damages of property. To avoid sparking while operating a maintenance switch, the switch has to meet high technical requirements.

Our brochure ATEX 2011/2012 shows a summary of the new Kraus & Naimer ATEX maintenance switches suitable for zone 21, including 3 to 4 pole switches up to 55 A and 6 pole switches up to 32 A.
