Schneider Electric LR1-D09308 Thermal Overload Relay

The Schneider Electric Telemecanique LR1D09308 thermal overload relay is a 3-pole motor protection device for three‑phase motors, with an adjustable current range of 2.5–4 A and Class 10A trip characteristics, rated up to 600 VAC (690 VAC IEC). It mates with Telemecanique LC1D and LP1D motor starters and contactors, supports Direct Mount or Panel Mount installation, and uses screw‑Clamp terminals with 2 normally open and 2 normally closed auxiliary contacts for control logic. Common applications include motor control centers, conveyors, pumps, compressors, HVAC equipment, packaging machinery, and other industrial automation systems requiring reliable motor protection and phase‑failure protection.
