Telemecanique LRD126 Three-Phase Thermal Overload Relay

The Telemecanique LRD126 three-pole thermal overload relay protects three‑phase motors against overload and phase failure when used with TeSys D contactors. It offers an adjustable overload range of 5.5–8 A and Class 10A tripping, and is rated for 690 VAC (600 VAC UL/CSA). The unit provides one normally open and one normally closed auxiliary contact and mounts via Direct Contactor Mount, DIN rail, or panel with accessories, using screw-clamp terminals for secure wiring. Compatible TeSys D contactors include LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38. The relay is part of TeSys LRD (TeSys Deca) series, manufactured by Telemecanique (Schneider Electric), and is designed as an OEM direct replacement for systems relying on LRD126. Typical applications span motor control centers, conveyors, pumps, compressors, fans, HVAC equipment, and manufacturing machinery in which dependable motor protection helps maintain uptime and extend motor life.
