Schneider Electric LR2D3361 Thermal Overload Relay

The Schneider Electric LR2D3361 Thermal Overload Relay is a 3-pole protective device that mounts directly to TeSys contactors for industrial motor protection. It provides adjustable overload protection for three-phase motors with an adjustable current range of 55–70 A and a rated operational voltage up to 600 VAC, using thermal bimetallic sensing and offering phase-loss sensitivity. The relay offers a Class 10A trip class and a reset that can be either manual or automatic, making it suitable for motor starter assemblies in motor control centers, conveyors, pumps, compressors, HVAC equipment, and automated machinery. It is IEC, UL Listed, and CSA Certified, and is commonly replaced by Schneider Electric LRD3361, Siemens 3RU2146-4JB0, or Eaton XTOLR070 when maintenance or retrofits are performed.
