Key specifications

• Power rating: 3 kW
• Voltage: 690 V AC
• Phase: 3-phase
• Current range: 1.25-5 A (adjustable)
• Protection rating: IP40
• Dimensions: 45 mm width, 60 mm depth, 66 mm height
• Tripping class: 10

How to use

The LUCA05FU control unit is designed to be inserted directly into compatible LUB power bases. Once installed, the current settings should be adjusted according to the specific motor load requirements. Control is managed through the terminals located on the power base. Ensure all electrical connections are tightened to the manufacturer's specifications before energizing the system to prevent loose contact or overheating.

What to consider before purchase

• Verify compatibility with your existing LUB power base model.
• Ensure the motor current falls within the 1.25-5 A adjustable range.
• Check that the installation environment meets the IP40 protection requirements.
• Confirm the control voltage requirements for your specific automation setup.

Usage recommendations

Always perform a functional test after installation to ensure the overload and short-circuit protection settings are correctly calibrated for your motor. Regularly inspect the unit for signs of wear or environmental damage to maintain operational safety.
