Schneider Electric LRD10 Thermal Overload Relay 4-6A

The Schneider Electric LRD10 thermal overload relay is a precision-engineered component designed to provide robust protection for electric motors within industrial electrical systems. With an adjustable current range of 4-6A, this device effectively monitors current flow to prevent damage caused by overloads or phase failures. Its reliable design ensures that connected equipment operates safely and efficiently, minimizing downtime and extending the service life of motors in demanding environments.

Advantages

This thermal overload relay offers exceptional reliability and ease of integration into existing motor control circuits. The adjustable current setting allows for precise calibration to match the specific requirements of the motor, ensuring optimal protection levels. Its compact and durable construction is built to withstand the rigors of industrial applications, providing consistent performance and peace of mind for facility managers and electrical engineers alike.

Suitable for

• Industrial motor control systems
• Protection against motor overload
• Phase failure detection
• Electrical panel integration

This device may not be suitable for applications requiring current ranges outside of the 4-6A threshold. It is specifically designed for motor protection and should not be used as a general-purpose circuit breaker or for high-voltage distribution systems beyond its rated insulation capacity.

Key specifications

• Adjustable current range: 4-6A
• Rated insulation voltage: 690V
• Weight: 124g
• Design: Thermal overload protection

Installation should be performed by a qualified professional in accordance with local electrical regulations. The relay is typically mounted directly to a compatible contactor. Ensure that the current setting is adjusted to the full-load amperage of the motor being protected before energizing the system. Regularly inspect the device for signs of wear or thermal stress to maintain operational safety.

What to consider before purchase

• Verify the full-load current of your motor falls within the 4-6A range
• Ensure compatibility with your existing contactor model
• Check that the installation environment meets the specified voltage requirements

Usage recommendations: Always perform a functional test after installation to ensure the relay trips correctly under simulated overload conditions. Keep the device free from dust and moisture to ensure long-term reliability.
