Schneider Electric LRD32C Thermal Overload Relay With Class 10A Fast Tripping

📋 Product Overview

What it does Schneider LRD32C is a 3‑pole differential thermal overload relay belonging to TeSys Deca series. It works paired with LC1D series AC contactors, offering motor thermal overload and phase‑failure protection. Adopting Class 10A fast tripping characteristic, it quickly cuts off circuit when motor suffers over‑current, locked‑rotor or phase‑loss fault, preventing motor winding burnout. It comes with 1NO+1NC auxiliary contacts for fault signal feedback to PLC or alarm system, widely used inside electrical control cabinets for three‑phase asynchronous motors.

✨ Product Advantages / Core Features

• ✅ Class 10A Fast Tripping: Fast response under locked‑rotor condition, trips within 2‑10s at 7.2× setting current, well‑suited for standard AC induction motors
• ✅ Built‑in Phase‑failure Sensitivity: Differential structure, fast tripping upon single‑phase loss to avoid motor damage from unbalanced power supply
• ✅ Dual Reset Mode: Manual reset (blue reset button) + manual stop (red stop button); supports optional auto‑reset by modification, convenient for on‑site operation
• ✅ Ambient Temperature Compensation: Stable tripping performance within ‑20℃ ~ +60℃, no need for derating under normal cabinet environment
• ✅ Direct Plug‑in Installation: Can be snapped directly beneath LC1D25 / LC1D32 / LC1D38 contactors, saves cabinet mounting space; also supports DIN‑rail or panel mounting with accessories
• ✅ 1NO +1 NC Auxiliary Contacts: Independent fault signal output for alarm, interlock and remote monitoring signal transmission
• ✅ Global Certifications: Complies with IEC 60947‑4‑1, UL, CSA, CE, UKCA, suitable for global export projects
• ✅ IP20 Touch‑safe Terminal: Prevent accidental touch for operator safety inside control cabinet
