Description
TeSys LRD thermal overload relay, 32A/690V, thermal setting range 23-32A, tripping class 10A, for protection of 3-phase motors 15kW@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 EverLink BTR screw terminals , it connects directly to the bottom terminals of 3-pole contactors LC1D40A-D80A. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD96560 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHs/Reach).
Features
- Featuring an adjustable dial calibrated from 23 to 32 Amps, this relay allows industrial technicians to match the exact full-load amperage (FLA) listed on their motor's nameplate. This precise tuning eliminates frequent nuisance trips during intense startup cycles while ensuring rigorous, code-compliant thermal protection for mid-range pumps, fans, and compressors.
- Engineered for seamless mechanical integration, the LRD332 mounts directly beneath Schneider Electric's TeSys Deca LC1D40A through LC1D65A 3-pole contactors. This plug-and-play connection eliminates the need for extra interconnecting wires or external mounting brackets, maximizing available rail space and dramatically reducing assembly time for commercial panel builders.
- Built with advanced differential mechanism logic, the LRD332 automatically compensates for ambient temperature variations and rapidly detects an unbalance or total loss of a phase. By tripping the control circuit before winding heat can spike dangerously, it saves high-value three-phase motors from catastrophic insulation breakdown and failure.
- Operating on a rigorous Class 10A trip curve, this relay guarantees a reliable circuit disconnect within 10 seconds of encountering a locked-rotor or 600% overload condition. This standardized timing provides optimal thermal protection for general-purpose applications like conveyors, fans, and pumps, ensuring code-compliant safety.
