To switch industrial circuits on and off efficiently, pick this contactor from Siemens. A contact current rating of 65A and a contact voltage rating of 400V AC mean it can handle high-power applications, including lighting, motor and heating controls. It has a rugged and climate-proofed construction, so operates safely in temperatures between -25°C and +60°C. This enables it to cope with the harsh conditions found in manufacturing and plant engineering environments. The unit's fitted with two auxiliary contacts that have a reliability of one faulty switch per 100 million operations, so you can be sure it's dependable. As part of the SIRIUS range, this contactor is easy to combine with a motor starter and current-monitoring relay, so you can build a complete and customised control system for your application.

• Dimensions of 55 (W) x 114 (H) x 130mm (D) mean it's easy to handle
• Short-circuit protection to minimise electrical damage to the main circuit
• Suitable for mounting with a slight tilt and at a 180° rotation, for installation flexibility

The contactor has an expected mechanical lifespan of 10,000,000 switching cycles. This makes it a durable option for industrial control panels.
