Description
TeSys LRD thermal overload relay, 38A/690V, thermal setting range 30-38A, tripping class 10A, for protection of 3-phase motors 18.5kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D32-D38. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD7B106 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), Green Premium compliant (RoHs/Reach).
Features
- Engineered for high-precision 3-phase motor protection, this thermal overload relay allows you to strictly dial in the exact full-load amperage of your equipment between 30 and 38 amps. Setting the correct operational threshold prevents expensive stator winding damage from sustained overcurrents, dramatically extending the operational lifespan of your industrial pumps, compressors, and heavy material conveyors.
- Built to tolerate standard, harmless inrush currents during motor boot-up, the Class 10A rating safely absorbs short-duration surges while reliably reacting to prolonged overloads. This intelligent thermal profile eliminates frustrating unplanned downtime in busy automation control panels, ensuring your heavy-duty machinery starts smoothly while remaining strictly protected against electrical faults.
- Continuously monitoring electrical current across all three poles, this advanced safety device instantly detects dangerous phase drops or severe voltage unbalances that standard circuit breakers often miss. By rapidly opening the motor starter circuit before critical overheating and insulation breakdown can occur, it proactively safeguards your valuable industrial hardware and drastically reduces emergency facility maintenance budgets.
- Designed for seamless mechanical integration into high-density electrical enclosures, this TeSys Deca relay mounts directly underneath standard Schneider LC1D32 and LC1D38 contactors using secure, vibration-resistant screw-clamp terminals. This highly efficient, OEM-compliant footprint speeds up both new motor panel building and routine retrofitting, while providing built-in 1NO/1NC auxiliary contacts for instant fault signaling directly to your PLC.
