Product Overview
The Schneider Electric LR2K0307 is a TeSys K / TeSys LRK differential thermal overload relay designed to protect industrial motors against overload conditions, phase failure and current unbalance. It features an adjustable thermal protection range of 1.2-1.8A and a Class 10A tripping characteristic conforming to IEC 60947-4-1. The relay uses thermal bimetallic protection technology and provides one normally open (1NO) and one normally closed (1NC) auxiliary contact for trip signalling and control circuits. Its front panel includes a manual/automatic reset selector, red trip test button, blue stop/manual reset button and trip indicator. The LR2K0307 is designed for direct mounting under compatible TeSys K contactors, including LC1K, LC7K, LP1K and LP4K families. Separate rail or plate mounting is possible with dedicated accessories, including the LA7K0064 terminal block, which is sold separately. The compact relay measures 45 x 58 x 65mm (W x H x D) and features screw-clamp terminals and IP2X protection. The supplied product and packaging photographs confirm the LR2K0307 model and its 1.2-1.8A thermal setting range. The relay must be adjusted to the applicable motor full-load current and used with appropriate upstream short-circuit protection.
