Schneider Electric LRD08 Thermal Overload Relay

The Schneider Electric LRD08 TeSys LRD thermal overload relay is a three-pole motor protection device designed to guard three‑phase motors from overload and phase-failure when used with TeSys D contactors. It offers an adjustable overload current range of 2.5–4 A with class 10A trip characteristics and supports operation up to 690 VAC (600 VAC UL/CSA). It provides one normally open and one normally closed auxiliary contact and can be mounted directly on a contactor, on a DIN rail, or on a panel with the appropriate accessories; it uses screw-clamp terminals for wiring. Compatible TeSys D contactors include LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38, and it is commonly installed in motor control centers, conveyors, pumps, compressors, fans, HVAC equipment, and manufacturing machinery to deliver reliable motor protection across industrial applications.
