Schneider Electric LR1-D09307 Thermal Overload Relay

Schneider Electric Telemecanique LR1-D09307 thermal overload relay, Series LR1D, is a three-pole motor protection device with an adjustable current range of 1.6–2.5 A and Class 10 trip characteristics, designed to guard three-phase motors against overload and phase-failure conditions in demanding industrial environments. It supports up to 600 VAC maximum rated voltage (660 VAC insulation), provides two normally open and two normally closed auxiliary contacts, and can be mounted directly on a frame or panel; it uses screw clamp terminals and is compatible with Telemecanique LC1D and LP1D motor starters and contactors. Commonly installed in motor control centers, conveyors, pumps, compressors, packaging machinery, HVAC equipment, and other automation systems, this thermal overload relay delivers adjustable overload and phase-failure protection and is offered as an OEM direct replacement for LR1D09307.
