Schneider Electric LRD12 Thermal Overload Relay

Schneider Electric LRD12 Thermal Overload Relay, part of the TeSys LRD family and commonly paired with TeSys D contactors, is a three-pole motor protection device that guards three-phase motors against overload and phase loss. It provides an adjustable overload current range of 5.5–8 A and Class 10A tripping characteristics, with a rated voltage of 690 VAC (600 VAC UL/CSA). The relay features 1 NO + 1 NC auxiliary contacts, a screw-clamp terminal, and mounting options including Direct Contactor Mount, DIN Rail, or Panel Mount (with accessories). It is compatible with TeSys D contactors LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38. Operating temperature ranges from -20°C to +60°C. This device serves as an OEM direct replacement for the LRD12 family and is widely used in motor control centers, conveyors, pumps, compressors, fans, HVAC equipment, packaging machinery, machine tools, and other industrial control panels that rely on TeSys D motor starters for reliable motor protection.
