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 40 amp through 65 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 37 to 50 amperes. This trip current rating is calibrated per Class 10A. This overload relay uses EVERLINK termnals in place of the standard terminals.
Features
- Specifically engineered for seamless plug-and-play mounting beneath TeSys Deca and TeSys D contactors (models LC1D40A through LC1D65A), this thermal overload relay creates a compact, high-integrity motor starter assembly. By utilizing a direct-connect design, you eliminate additional wiring labor and reduce the overall footprint within your industrial control panel.
- Featuring a precision-calibrated adjustment dial, this relay allows you to fine-tune the protection threshold between 37 and 50 Amps to match your motor's full load amperage (FLA). This granular control prevents premature motor burnout due to subtle overloads while simultaneously reducing nuisance tripping, ensuring your 3-phase pumps, fans, or conveyors operate at peak efficiency.
- Built with advanced differential tripping technology, this relay monitors for phase unbalance or the total loss of a single phase a common cause of rapid motor overheating and catastrophic failure. This proactive sensing mechanism instantly disconnects the motor during a phase fault, saving you thousands of dollars in rewinding costs and preventing unplanned production downtime.
- Equipped with a versatile blue reset button and a dedicated red stop/test button, this unit allows maintenance teams to choose between manual reset for critical fault investigation or automatic reset for remote applications. The visible trip indicator and built-in NO+NC auxiliary contacts provide immediate feedback to your PLC or alarm system, allowing for rapid diagnostics and a safer return to operation after an overcurrent event.
- Fully compliant with international standards including UL 508, CSA C22.2, and IEC 60947-4-1, this TeSys LRD relay is suitable for use in demanding global markets. Whether you are building panels for a domestic manufacturing plant or exporting machinery overseas, this certified protection ensures your equipment meets all mandatory safety regulations and electrical codes for motor branch circuit protection.
