Schneider Electric LRD32 Thermal Overload Relay 23-32A

The Schneider Electric LRD32 thermal overload relay is a high-quality protection device engineered to safeguard electric motors from damage caused by overloads or phase failures. This component is specifically designed for industrial electrical systems, providing reliable monitoring and disconnection capabilities to ensure the longevity and operational safety of connected equipment. With its precise current adjustment range and robust construction, it serves as a critical element in modern automation and control panels.

Advantages

This thermal overload relay offers exceptional reliability and durability in demanding industrial environments. Its adjustable current setting allows for precise calibration to match the specific requirements of the motor, ensuring optimal protection without nuisance tripping. The compact design facilitates easy integration into existing control systems, while the high insulation voltage rating provides an additional layer of safety and performance stability during operation.

Suitable for

• Industrial motor control circuits
• Automation and control panels
• Protection against motor overload
• Phase failure detection in electrical systems

This device may not be suitable for applications requiring protection against short-circuit currents, as it is designed specifically for thermal overload protection. It should not be used as a standalone circuit breaker or in environments where the ambient temperature exceeds the manufacturer's specified operating limits.

Key specifications

• Current adjustment range: 23-32A
• Rated insulation voltage: 690V
• Weight: 124g
• Colour: Multicolour

To use the Schneider Electric LRD32, mount the device directly onto the corresponding contactor. Once installed, adjust the dial on the front of the unit to the nominal current rating of the motor being protected. Ensure all electrical connections are tightened to the specified torque values to prevent overheating at the terminals. The device is designed to automatically trip the control circuit when an overload condition is detected, preventing potential motor burnout.

What to consider before purchase

• Verify that the motor's full-load current falls within the 23-32A range
• Ensure compatibility with your existing contactor model
• Check that the installation environment meets the required thermal and electrical standards

Usage recommendations: Regularly inspect the relay for signs of wear or damage and perform periodic testing of the trip mechanism to ensure continued protection of your electrical equipment.
