Telemecanique LR1-D09305 Thermal Overload Relay

Telemecanique LR1D09305 thermal overload relay is a three-pole motor protection device that guards 3‑phase motors from overload and phase loss, featuring an adjustable overload current setting of 0.63–1 A and Class 10 tripping characteristics. It supports a maximum rated voltage of 600 VAC (690 VAC IEC) and is designed to pair with Telemecanique LC1D and LP1D contactors for reliable motor starter protection in industrial control systems. The unit uses screw-clamp terminals and provides 2 normally open plus 2 normally closed auxiliary contacts, enabling flexible wiring and interlocking within control circuits. Mounting options include direct mount or panel mount, allowing integration into motor control centers, control panels, or machine enclosures. Common applications span conveyors, pumps, compressors, packaging machinery, HVAC equipment, and other industrial automation environments where dependable low-current motor protection is required. As an OEM direct replacement, it aligns with Schneider Electric’s LR1D family, ensuring compatibility with existing LR1D‑series protection schemes and replacement workflows.
