LRD340C - Telemecanique TeSys Deca Thermal Overload Relay 30-40A 690V Class 10A

LRD340C

LRD340C is a TeSys Deca thermal overload relay designed to protect AC circuits and motors against overloads, phase failure, and prolonged stalling. This compact relay mounts directly under LC1D40A to LC1D65A contactors and features manual or automatic reset capability. LRD340C delivers reliable motor protection with a thermal setting range of 30 to 40 amperes and rated voltage of 690 VAC. The relay incorporates phase failure sensitivity with a tripping current of 130 percent of rated current on two phases. Temperature compensation operates from -20 to 60 degrees Celsius, ensuring consistent performance across varying ambient conditions. Control connections use screw clamp terminals rated for 1 to 2.5 mm_ flexible cable, while power circuit connections employ EverLink BTR screw connectors rated for 1 to 35 mm_ solid cable.
