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 9 amp through 38 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 16 to 24 amperes. This trip current rating is calibrated per Class 10A. Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine).
Features
- The Schneider LRD32 is a differential thermal overload relay designed to protect AC motors against overloads, phase failure, long starting times, and prolonged stalling of the motor. It is engineered to mount directly beneath a TeSys D contactor (specifically models LC1D25 through LC1D38), creating a compact and highly reliable motor starter assembly.
- Featuring a versatile adjustment dial, the LRD32 covers a current range of 23 to 32 Amps. This allows maintenance technicians to precisely calibrate the protection level to match the specific nameplate rating of the motor, ensuring the system only trips under genuine fault conditions while preventing "nuisance trips" during standard operation.
- This relay features advanced differential protection, which monitors the balance between all three phases. If one phase is lost or significantly unbalanced a common cause of rapid motor burnout the LRD32 will trip the circuit immediately, saving the motor from catastrophic internal damage and avoiding costly unscheduled downtime.
- The LRD32 offers maximum flexibility with a dual-function Manual/Auto reset selector. In "Manual" mode, an operator must physically press the reset button after a fault, ensuring a safety check is performed. In "Auto" mode, the relay resets itself once the bimetallic strips have cooled, making it ideal for remotely located pumps or fans where manual intervention is difficult.
- To simplify troubleshooting, the unit includes a trip indicator flag and a dedicated Test trip button. The test button allows you to manually actuate the NC (Normally Closed) and NO (Normally Open) auxiliary contacts to verify that your control logic and alarm circuits are functioning correctly without needing to create an actual overload condition.
