Make quick work of turning your equipment off and on with this 3NO contactor from Siemens. It achieves up to 5.5kW while using only around 0.9W of electricity at 400V, so it's suitable for energy-efficient IE3/4 systems. Snap-on mounting makes the unit quick and easy to install on a standard 35mm DIN rail. An IP20 rating means you can be sure it's touch-proof and safe to handle without the risk of shocks. Thanks to a high current rating of 12A, this component powers up industrial three-phase motors in a jiffy.

• Screw terminals make wiring simple for quick installation and a vibration-proof connection
• Broad operating temperature range between -25°C and +60°C means it's reliable in demanding environments
• Compact dimensions of 45 (W) x 85 (L) x 97mm (D) so it fits into busy setups

Expect an opening delay between 4 and 16ms and a closing delay of 8 to 40ms. This means your contactor will turn off and on in the blink of an eye, so it's suitable for use with fast-paced machinery.
