Key specifications

• Number of poles: 3
• Rated current: 20 A
• Rated operational voltage: 380-415 V AC
• Application: Electrical circuit isolation

How to use

The Hager HAB302 should be installed by a qualified electrician within a suitable electrical enclosure or distribution board. Ensure that the power supply is completely disconnected before beginning the installation process. Mount the device securely onto the DIN rail or mounting plate as required by the enclosure design. Connect the input and output cables to the corresponding terminals, ensuring that all connections are tightened to the manufacturer's specified torque settings to prevent overheating or loose contacts.

What to consider before purchase

• Verify that the 20 A current rating matches your circuit requirements.
• Ensure the 380-415 V voltage range is compatible with your electrical system.
• Confirm that the enclosure has sufficient space for a 3-pole device.
• Check local electrical regulations regarding the installation of isolating switches.

Usage recommendations

Always perform a functional test after installation to ensure the switch operates smoothly and effectively disconnects the power supply. Regularly inspect the terminal connections for signs of wear or loosening during routine maintenance cycles.
