Details for LRD22

Schneider Electric (Square D) LRD22 16/24A IEC Overload Relay Schneider Electric's LRD22 overload relay (SKU: LRD22) is a reliable and precise protection device designed to safeguard your electrical systems from damage caused by overloads and short circuits. This versatile relay features an adjustable tripping range of 16 to 24A, making it suitable for various applications. The LRD22 is built with robust construction and high-quality components, ensuring long-lasting performance in demanding industrial environments. It utilizes precision-engineered mechanisms to accurately detect current overloads and quickly trip the circuit to protect your equipment and wiring. Its compact design allows for easy installation in control panels or enclosures. Key Features: Adjustable tripping range: 16 to 24A IEC standard compliance Manual and automatic reset options Thermal protection against overloads Compact and robust design Applications: Motor protection in industrial machinery Control and protection of electrical circuits Overload protection for pumps, fans, and compressors Maintenance professionals and industrial engineers trust the Schneider Electric (Square D) LRD22 overload relay for its reliability, accuracy, and long service life. Choose our HVAC supply store for the best prices and fast shipping on premium products like the LRD22! 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. Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), Green Premium compliant (RoHs/Reach).
