Schneider Electric LRD332 TeSys D Thermal Overload Relay

Description

The LRD332 is a professional-grade thermal overload relay from the TeSys D range, engineered by Schneider Electric to provide reliable motor protection against overloads and phase failures. Designed with a current adjustment range of 23–32 A and a Class 10A trip class, this relay is built for efficiency and safety in industrial motor control circuits. The inclusion of EverLink BTR terminal technology ensures long-term connection reliability, effectively reducing the need for periodic retightening and maintenance.

Features

• Protection Range: Adjustable setting range from 23 A to 32 A
• Trip Class: Class 10A for standard motor starting applications
• Connection Technology: EverLink BTR screw connectors for superior, vibration-resistant contact quality
• Durability: Robust construction designed for continuous industrial operation
• Compatibility: Designed for integration with TeSys D contactors

Applications

• Industrial motor control centers (MCCs)
• Pump and fan control systems
• Conveyor belt and material handling motors
• Compressors and HVAC motor starters
• General industrial machine automation

Installation Guidelines

• Integration: Mount the LRD332 directly onto a compatible TeSys D contactor for a compact, integrated starter solution, or use an independent mounting kit if required.
• Setup: Use the adjustment dial on the front of the unit to set the trip current according to the motor's full-load amperage (FLA) rating.
• Wiring: Utilize the EverLink BTR terminals to secure conductors. Ensure cables are stripped to the correct length to achieve the full benefit of the EverLink connection technology.
• Testing: Use the manual test function to simulate a trip and verify the functionality of the auxiliary contact monitoring circuit before full system startup.
