OVERLOAD RELAY: LRD332 from Schneider Electric (Square D) The LRD332 Overload Relay from Schneider Electric (Square D) provides protection for your motors in industrial applications. This relay automatically detects and interrupts current overloads to prevent damage to your equipment. Key Features * Protects motors from electrical overloads * Adjustable trip range for precise protection * Easy to install and adjust * Reset button for convenient operation * Compliant with UL, CSA, and IEC standards Applications * Industrial machinery * Motor control panels * Pumps and compressors * Conveyors and material handling systems Benefits * Extends motor life by preventing overloads * Protects equipment from damage * Ensures safe and reliable motor operation * Meets industry standards for safety and performance Order your LRD332 Overload Relay today from our HVAC supply store and experience the exceptional protection and reliability of Schneider Electric (Square D) products. We offer competitive prices, fast shipping, and expert support for all your electrical needs. TeSys LRD overload relays are designed to be used with TeSys D contactors to make a motor starter. This overload relay can be used with 9 amp through 38 amp TeSys D contactors. These differential thermal overload relays detect over currents in the lines to the motor. When an overcurrent is detected the overload relay working with the contactor will disconnect the power to the motor. This will minimize the damage to the motor windings. This overload relay has an adjustable trip current rating of 16 to 24 amperes. This trip current rating is calibrated per Class 10A. This overload relay uses EVERLINK termnals in place of the standard terminals.
