Power up equipment in a flash with this 3NO contactor from Siemens. It has a power rating of 7.5kW and uses just 1.8W of electricity, so it's an energy-efficient choice. As the unit has a long mechanical life of 1 million cycles, you can be sure of its reliability. Dimensions of 45 (W) x 97 (D) x 85mm (L) mean it's compact enough to slot neatly into tight spots. A switching frequency of up to 5,000 switches per hour makes this contactor suitable for demanding applications like electric motors and lighting systems.

• IP20 rating means it's touch-proof and shielded from objects larger than 12mm so it's safe to handle
• Wide operating temperature range between -25°C and +60°C for use in demanding conditions
• Fast opening delay between 4 and 16ms means speedy reactions
• Screw terminals make installation simple and connections secure

You can mount this contactor onto a standard 35mm DIN rail or on a vertical mounting surface. If installed vertically, the unit can be tilted backward or forward up to 22.5° to make it easier to reach.
