This 3-pole isolator switch from Siemens is designed to disconnect an extractor fan, air conditioner or refrigerator from its electrical supply. It interrupts the flow of input current from the main power source, giving you safe access to the device. The black plastic knob turns smoothly between the resting, on and off positions, so it's easy to control. For added safety, you can padlock it to prevent tampering. The unit's compact dimensions of 66 (length), 49 (width) and 89.5mm (depth) mean it takes up minimal space on a control panel. An IP65 (ingress protection) rating means it's protected from dust and low-pressure water jets, making it a good choice for use in demanding industrial environments.

• Long mechanical lifespan of 100,000 switching cycles for long-lasting performance
• Wide operating temperature range of -25°C to +55°C for use in demanding environments
• Surge voltage resistance of 6000V for robust protection against electrical surges

Yes, you can use this unit to switch your electrical device between the on and off state, making it the main control switch.
