Motorbeveiligingsschakelaars Ex9S schakelen motoren handmatig in en uit en bieden zekeringloze beveiliging tegen kortsluiting en fase-uitval. Bij kortsluiting schakelen ze snel af, waardoor schade aan motor en installatie wordt beperkt. Motorbeveiligingsschakelaars kunnen worden gecombineerd met contactoren en thermische overbelastingsrelais.
