Schneider Electric LRD332 Thermal Overload Relay – 23–32A – TeSys Deca Series – DIN Rail/Plate Mount – Motor Protection Relay for LC1D40A/50A/65A Contactors

The Schneider Electric LRD332 is a 3-pole thermal overload relay from the TeSys Deca series, designed to protect three-phase motors from overload conditions. It works in combination with LC1D-series contactors to ensure safe motor operation by disconnecting the circuit when excessive current or prolonged overload is detected.
