Overview

Details for LR2K0312

LR2K0312 Schneider Electric (Square D) Overload Relay The LR2K0312 Overload Relay from Schneider Electric (Square D) is an essential component for protecting electrical equipment from potential damage caused by overloads. Featuring a current range of 3.8/5.5A, this overload relay effectively monitors and interrupts the flow of electricity when excessive current is detected. It ensures the safety of electrical circuits and connected equipment, preventing costly breakdowns and downtime. Built with precision and reliability, the LR2K0312 Overload Relay is designed to operate in demanding industrial environments. Its rugged construction offers durability and long-term performance, while its compact size allows for flexible installation in various electrical systems. Key Features: * Current Range: 3.8/5.5A * Protects electrical circuits from overloads * Monitors and interrupts excessive current flow * Ensures equipment safety and reliability * Durable construction for industrial applications * Compact size for versatile installation Applications: The LR2K0312 Overload Relay is ideal for use in a wide range of industrial applications, including: * Motor protection * Circuit protection * Equipment safety * Industrial automation Our HVAC supply store offers competitive pricing and fast shipping on the LR2K0312 Overload Relay. For the best deals and exceptional service, choose Our HVAC supply store for your industrial 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).
