Description

TeSys LRD overload relays are designed to be used with TeSys D contactors to make a motor starter. This overload relay can be used with 115 amp through 150 amp TeSys D contactors. These differential thermal overload relays detect over currents in the lines to the motor. When an overcurrent is detected the overload relay working with the contactor will disconnect the power to the motor. This will minimize the damage to the motor windings. This overload relay has an adjustable trip current rating of 80 to 104 amperes. This trip current rating is calibrated per Class 10A. Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine).

Features

The TeSys Deca LRD4365 features a wide thermal protection adjustment range of 80 to 104 A, allowing precise calibration to your specific motor s full-load current (FLC) via an integrated bimetallic adjustment dial. This granular control eliminates unnecessary operational downtime caused by nuisance trips during startup while providing responsive, tight thermal protection under continuous heavy load conditions.
Engineered for seamless integration, this differential thermal overload relay mounts directly beneath 3-pole TeSys D contactors specifically models LC1D115 and LC1D150 using rugged lug clamps. This direct-coupling feature saves critical enclosure space, cuts down assembly and wiring layout times, and guarantees standard-compliant electrical coordination without the need for standalone terminal blocks.
Built with integrated phase failure and load unbalance detection, the relay automatically triggers a Class 10A trip if a single phase drops out or an uneven load condition occurs, conforming to IEC 60947-4-1 standards. By quickly disconnecting the circuit before severe winding overheating occurs, it protects high-value 45 kW (at 400V) motors from catastrophic, unrepairable single-phasing burnouts.
This unit comes fully equipped with a red manual stop button, a blue reset button that configures easily between manual or automatic reset modes, an integrated trip indicator flag for visual troubleshooting, and a dedicated test button to simulate electrical tripping. Combined with standard built-in 1 NO + 1 NC auxiliary contacts for remote fault signaling, it provides immediate control circuit feedback to your PLC or pilot lights to accelerate troubleshooting routines.
The LRD4365 meets demanding global engineering standards with UL 508, CSA C22.2, IEC 60947-4-1, CE, and ATEX certifications, ensuring full code compliance across Canadian and international industrial projects. Additionally, it is certified as a Green Premium product, featuring full RoHS and REACH compliance along with optimized end-of-life recycling potential for sustainability-driven operations.
