Product Overview
The Schneider Electric LR2K0306 is a TeSys K / TeSys LRK differential thermal overload relay designed to protect industrial motors against overload conditions and phase failure. It features an adjustable thermal protection range of 0.8-1.2A and a Class 10A tripping characteristic conforming to IEC 60947-4-1. The relay uses a thermal bimetallic protection mechanism with phase failure sensitivity and provides one normally open (1NO) and one normally closed (1NC) auxiliary contact for signalling and control functions. The device includes a manual/automatic reset selector, red trip test button, blue stop/manual reset button and yellow trip indicator. It is designed for direct mounting under compatible TeSys K contactors, including LC1K, LC7K, LP1K and LP4K families. Separate mounting is also possible with specific accessories, such as the LA7K0064 terminal block. The compact relay measures 45 x 58 x 65mm (W x H x D) and features screw clamp terminals and IP2X protection. The supplied actual product and packaging photographs confirm the exact LR2K0306 model and 0.8-1.2A current adjustment range. The thermal setting must be selected according to the motor nameplate current, and separate short-circuit protection must be provided in the motor circuit.
