Schneider Electric LR2K0306 Thermal Overload Relay, 0.8-1.2A

The Schneider Electric LR2K0306 is a high-quality thermal overload relay engineered to provide robust protection for electric motors. With an adjustable current setting range of 0.8 to 1.2A, this device is specifically designed to detect and prevent damage caused by thermal overloads or phase imbalances. It serves as a critical safety component in industrial control circuits, ensuring that motors operate within their intended electrical parameters to prevent overheating and premature failure.

Advantages

This thermal overload relay offers exceptional reliability and precision in monitoring motor current. Its compact design allows for efficient use of space within control panels, while its seamless compatibility with TeSys K contactors simplifies the installation process. By providing a dependable trip mechanism, it effectively safeguards equipment against electrical faults, thereby reducing downtime and maintenance costs in various industrial applications.

Suitable for

• Industrial motor control systems
• Protection of small electric motors
• Integration with TeSys K contactors
• Electrical panels requiring overload monitoring

When it may not be suitable

This relay is not intended for use with motors requiring a nominal current outside the 0.8 to 1.2A range. It is also not suitable for applications requiring advanced electronic motor management or communication features, as it is a dedicated thermal protection device.

Key specifications

• Adjustable current range: 0.8 to 1.2A
• Compatibility: TeSys K contactors
• Function: Thermal overload and phase failure protection
• Mounting: Direct mounting to contactor

How to use

The relay is designed for direct mounting onto compatible TeSys K contactors. Once physically attached, the main power cables are connected through the relay terminals to the motor. The current setting should be adjusted using the dial on the front of the device to match the full-load current rating of the motor being protected. After installation, the device should be tested to ensure the trip mechanism functions correctly under simulated fault conditions.

What to consider before purchase

• Verify the motor's full-load current rating falls within the 0.8-1.2A range
• Ensure compatibility with existing TeSys K contactor series
• Check the environmental conditions of the installation site

Usage recommendations

Always ensure that the power supply is disconnected before installing or adjusting the relay. Regularly inspect the device for signs of wear or thermal damage to maintain optimal protection levels.
