Use this isolator switch from Siemens to cut the power to an electrical circuit when you're carrying out maintenance. It's easy to operate – simply turn the black handle between the on and off positions. Thanks to a current rating of 32A, it's suitable for use in high-power systems. A long mechanical service life of 100,000 operating cycles means you can rely on this product for long-term performance. You'll commonly find it used with conveyor belts, process and packaging equipment and emergency stop systems.

• IP65 rating means it's dust-tight and protected against low-pressure water jets
• Compact size of 83 (H) x 67 (W) x 92.5mm (D) is easy to slot into busy setups

This isolator switch has a wide operating temperature range between -25°C and +55°C, so it's a good choice for use in harsh industrial environments.

A fused isolator switch like this one breaks the circuit using a fuse, while non-fused types break the circuit using a rotary switch or knife-blade disconnect. Fused isolator switches can handle higher loads than non-fused alternatives, so are suitable for use in demanding applications.
