Telemecanique LR2D1310 Thermal Overload Relay

The Telemecanique LR2D1310 Thermal Overload Relay is a three-pole, adjustable bimetallic protector designed for TeSys D/LC1D motor starters to safeguard three‑phase motors from overload and phase loss. With a current adjustment range of 4 to 6 A and a Class 10A tripping characteristic, it provides reliable protection for industrial motor control circuits up to 690 VAC, and it supports either manual or automatic reset for flexible recovery after protection events. This relay is commonly installed in motor starters, conveyors, pumps, compressors, and manufacturing equipment that require dependable thermal protection, and its phase-loss sensitivity helps detect loss of a phase and trip promptly to prevent motor damage. Its compatibility with TeSys D / LC1D contactors makes it suitable for motor control centers, electrical panels, and OEM machinery operating in demanding industrial environments. Applications span industrial automation, machine tools, HVAC equipment, and process control where robust overload protection is essential. For replacements or retrofits, common equivalents include Schneider Electric LRD10, ABB TA25DU-6.5, and Siemens 3RU2116-1FB0, reflecting the LR2D1310’s role as a compatible option within established motor-control ecosystems.
