Keep your motors ticking over with this 70A contactor from Siemens. You can use it to switch electrical loads and start, stop and set the direction of motors in industrial kit like pumps, fans and conveyors. As a three-pole, single-throw device, it's suitable for use with the three-phase electrical systems commonly found in industrial settings. Three sets of contacts in the NO position can be switched on to energise the circuit. With an operating temperature range of -25°C to +60°C, this climate-proof contactor does the job in challenging environments.

• 2 auxiliary contacts boost functionality to support activities like remote control or monitoring
• Contact voltage rating of 690 V AC makes it suitable for switching high-power loads
• Screw terminals help you make electrical connections quickly and easily

You can use a contactor to switch high-current loads that would be impractical or unsafe to handle with regular switches. As it suffers less wear and tear than a manual switch, you get a longer service life. Contactors can also be controlled remotely, so you can centralise your switching system.
