Details for LRD21
12-18A Overload Relay: LRD21 by Schneider Electric (Square D)The LRD21 overload relay from Schneider Electric (Square D) is designed to protect motors from overload and short-circuit conditions in industrial and commercial applications. This relay offers precise protection with its adjustable trip range of 12-18A.Key Features and Benefits:• Protects motors from overload and short-circuit currents• Adjustable trip range of 12-18A for customized protection• Compact design for easy installation in control panels• Manual and automatic reset options for flexibility• Long-lasting performance and reliabilitySpecifications:• Brand: Schneider Electric (Square D)• SKU: LRD21• Trip Range: 12-18A• Reset Type: Manual and Automatic• Applications: Industrial and Commercial Motor ProtectionTrust our HVAC supply store for the best prices and fast shipping on the LRD21 overload relay. Maintain the efficiency and safety of your industrial operations with this high-quality protective device! 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 12 to 18 amperes. This trip current rating is calibrated per Class 10A. Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), Green Premium compliant (RoHs/Reach).
