How to use
The Hager HAE412 should be installed by a qualified electrician into a compatible modular distribution system. Once mounted, the rotary handle allows for manual operation to switch the power supply on or off. To isolate the circuit, rotate the handle to the designated off position, ensuring the visible break mechanism has engaged. Always verify the status of the circuit using appropriate testing equipment before commencing any work on the downstream electrical system.
What to consider before purchase
Ensure the current rating of 125A is sufficient for your specific load requirements.
Verify that your electrical system operates within the 380-415V AC range.
Confirm that the modular dimensions are compatible with your existing distribution board layout.
Check local electrical regulations regarding the installation of rotary isolators in your specific application.
Usage recommendations
Always perform a functional test of the isolator after installation and before putting the circuit into regular operation. Ensure that the handle is accessible and clearly labeled to prevent unauthorized operation.
