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 80 amp through 95 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 55 to 70 amperes. This trip current rating is calibrated per Class 10A. Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine).
Features
- The LRD3361 features integrated phase imbalance and power loss detection to trigger a trip before high temperatures can permanently damage your motor windings. This proactive protection significantly extends the lifespan of your heavy-duty equipment and prevents the costly downtime associated with motor rewinding or replacement.
- This relay features a precise adjustment dial that allows you to match the trip current exactly to your motor's nameplate rating within the 55A to 70A range. This level of granularity ensures your 37kW to 45kW motors operate at peak efficiency without the risk of nuisance tripping or under-protection.
- Designed for seamless integration, the LRD3361 mounts directly beneath LC1D80 and LC1D95 contactors using EverLinkTM power terminal blocks. This direct-connect architecture reduces installation time, eliminates extra wiring labor, and creates a compact, vibration-resistant motor starter assembly perfect for crowded industrial control panels.
- Featuring a selectable reset mode (Manual or Automatic) and a dedicated stop/test button, this unit allows maintenance teams to quickly diagnose faults and verify circuit integrity. The blue reset plunger and red stop button provide clear tactile feedback, ensuring your facility can safely return to production as soon as the thermal fault is cleared.
