Schneider LR9D5367 3 Pole Differential Thermal Overload Relay Schneider LRD32C TeSys D Series

Schneider LR9D5367 and LRD32C are 3‑pole differential thermal overload relays belonging to TeSys D series. They work with TeSys D contactors to deliver comprehensive motor protection. The devices detect overload current, phase loss and phase unbalance for three‑phase AC motors, cutting off control circuit to stop motor operation upon fault conditions. They are widely used inside electrical cabinets to prevent motor burnout caused by over‑current, phase failure and abnormal load fluctuation.

• Differential phase‑loss & unbalance detection: Fast tripping for phase missing and unbalanced three‑phase load, enhances motor safety
• Precise adjustable current dial: Easy setting for matching motor rated current, visible scale for quick‑on‑site calibration
• Dual reset modes: Manual reset after tripping; stop & test button for regular function verification
• 1NO+1NC auxiliary contacts: Supports fault signal feedback for PLC, alarm lamp and remote monitoring system
• Direct plug‑on installation: Mount directly under matched TeSys D contactor, saves cabinet space and wiring work
• Transparent lockable protective cover: Avoid unintended parameter modification on site, suitable for harsh workshop environment
• Temperature‑compensated design: Stable tripping performance under wide ambient temperature range
• Multi‑standard certification: Compliant with IEC 60947‑4‑1, UL, CSA, RoHS for global industrial projects
