Furthermore, it meets international standards for safety and environmental compliance, making it a sustainable choice for modern industrial facilities.

Suitable for

• 3-phase motor control systems
• Industrial automation and machinery
• Electrical distribution panels
• Applications requiring motor protection up to 3 kW at 690 V AC

When it may not be suitable

This unit is not intended for use in environments requiring high ingress protection ratings, as it is rated IP40. It is also not suitable for applications outside of the specified voltage and current ranges or for systems that do not utilize the compatible TeSys U power base architecture.

Key specifications

• Power rating: 3 kW at 690 V AC
• System compatibility: 3-phase electrical systems
• Protection rating: IP40
• Dimensions: 45 mm width, 60 mm depth, 66 mm height
• Control voltage: 24 V DC
• Protection features: Overload, short circuit, phase loss, and insulation fault

How to use

To use the LUCA32BL, insert the control unit directly into a compatible TeSys U power base. Ensure that the power base is properly mounted and that all electrical connections are secure. The control terminals A1 and A2 on the power base should be connected to the 24 V DC supply to enable starter operation. Once installed, adjust the current settings according to the specific requirements of the connected motor to ensure accurate protection thresholds are established.

What to consider before purchase

• Verify compatibility with your existing TeSys U power base model
• Ensure the 24 V DC control voltage is available in your system
• Confirm that the motor current requirements fall within the adjustable range of the unit
• Check that the IP40 rating is sufficient for your installation environment

Usage recommendations

Always ensure that the power supply is disconnected before installing or performing maintenance on the control unit. Regularly inspect the connections and the status of the unit to ensure continued protection and optimal motor performance.
