Overview

Details for LR2K0312

Square D LR2K0312 Overload Relay: Essential Protection for Electrical Systems The Square D LR2K0312 Overload Relay is a critical component for safeguarding electrical systems against overloads and short circuits. Designed to trip and protect equipment at current levels between 3.8A and 5.5A, this relay ensures the safety and longevity of connected devices. With its compact size and easy installation, the LR2K0312 is ideal for use in various industrial and commercial applications. Its high-quality construction and reliable performance make it a trusted choice for professional electricians and maintenance engineers. Protect your electrical equipment and ensure safe operation with the Square D LR2K0312 Overload Relay. Our HVAC supply store offers competitive prices and fast shipping, making it the preferred destination for all your electrical supply needs. TeSys K overload relays are designed to be used with TeSys K contactors to make a motor starter. 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 3.7 to 5.5 amperes. This trip current rating is calibrated per Class 10A. Mounting on DIN rail, separated from the contactor, with use of a terminal block LA7K0064 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC), Green Premium compliant (RoHs/Reach).
