Schneider Electric LR3D32 Thermal Overload Relay

The Schneider Electric TeSys Deca LR3D32L thermal overload relay provides motor protection for 690 VAC circuits, acting when the winding temperature or current draw indicates overload on unbalanced loads, and is designed to interrupt power to the motor to prevent damage. Rated for 23 to 32 A in a 690 VAC system, LR3D32L carries 1 normally open and 1 normally closed contact, enabling you to drive a status indicator or a control circuit while still providing robust overload protection integrated with TeSys D contactors. The unit uses screw-terminal wiring, making field installation straightforward in panel cabinets, with a compact footprint suitable for TeSys LR.D assemblies, and it is part of Schneider Electric's TeSys LR.D family, designed to coordinate protection with motor starters. As a non-differential overload relay with class 20 protection (per LR3D32L listing), it is intended for unbalanced-load applications and is commonly used in industrial drives and HVAC motor circuits to prevent overheating and motor damage.
