Schneider Electric LRD16 Thermal Overload Relay

Schneider Electric LRD16 thermal overload relay (TeSys Deca) provides robust motor protection in TeSys D starter circuits by continuously monitoring the motor current in the 9–13 A range and mounting directly to TeSys D contactors to form compact, integrated control panels that save space and simplify wiring. It includes 1 normally open and 1 normally closed auxiliary contact, enabling essential interlock and feedback functions in both starting and stopping sequences, and it uses screw-clamp terminals for secure, vibration-resistant wiring, making field installation straightforward even in harsh industrial environments. With a class 10A thermal trip rating, the LRD16 offers ambient-compensated, bi-metallic thermal protection that responds to long-term overloads and voltage fluctuations, helping prevent motor damage during prolonged operation and occasional overload events. As part of Schneider Electric's TeSys Deca family, the LRD16 is designed for motor control applications in industrial panels, conveyors, pumps, and fans, providing reliable protection that coordinates with TeSys D contactors to support compact, scalable protection schemes. The 9–13 A current range suits small to mid-size motors, and its ambient-compensated, bi-metallic thermal element maintains protection accuracy across operating temperatures while screw-clamp terminals simplify wiring and improve reliability in rugged environments.
