Schneider Electric LRD05 Thermal Overload Relay

Schneider Electric TeSys Deca LRD05 thermal overload relay protects 690 VAC motor circuits by monitoring current in a 0.63 to 1 A range. It provides 1 normally open and 1 normally closed contact (Form A + Form B), enabling overload signaling while interrupting the appropriate circuit. The device uses screw-clamp terminals for secure wiring and carries a Class 10A trip rating to align with standard industrial motor protections. Designed to pair with TeSys Deca contactors, it forms a compact motor starter within Schneider Electric’s TeSys ecosystem. With an adjustable current setting across 0.63–1 A, the LRD05 accommodates varying motor full-load currents while operating up to 690 VAC. Typical applications include protection of three‑phase motors in conveyors, pumps, fans, and machine tools in high-voltage electrical environments, where TeSys Deca starters are specified. Its compact form factor and secure wiring simplify panel integration, delivering reliable overload protection without added relay space.
