Keep tight control of your powerful circuits with this 4-pole contactor from Siemens. A high voltage rating of 690V AC means it keeps pace with your equipment, while a lower voltage 110V AC coil supports safe switching. This means starting and stopping electric motors or turning lighting systems on and off isn't a risky business. The unit's easy to extend by simply snapping on auxiliary blocks and it conveniently clips together with other modules including motor starters and overload relays. This means it's a piece of cake to build your own bespoke system. A climate-proof coating ensures this contactor handles the demands of plant, processing and manufacturing environments.
