Take charge of your high-power equipment with this 3-pole contactor from Siemens. It uses a low-voltage input to open and close a 690V circuit, so it's a safe way to control applications like electric starter motors and lighting installations. Thanks to its 2 auxiliary contacts, the robust unit can easily handle current spikes and other electrical hazards, so it protects your equipment in fault conditions. A straightforward screw termination method gives you long-lasting connections you can rely on. The 3NO configuration means no current flows until you flick the switch, so your machinery won't power up until you're ready.

• Compact dimensions of 45 (W) x 97 (D) x 85mm (L) mean it fits comfortably in cramped spots
• Wide operating temperature range between -25°C and +60°C so it's reliable in extreme conditions
• 15kW maximum operating power means it can easily handle heavy-duty industrial tasks

Yes – this contactor has a finger-safe IP20 rating so you won't get an electric shock if you touch the surface while it's running.
