Schneider LRD16C Thermal Overload Relay IP20 Overcurrent Protection

📌 Product Overview

The Schneider LRD16C is a thermal overload relay designed for motor overcurrent protection. It works in combination with contactors in motor control circuits. This relay detects abnormal motor current rise caused by overload, locked rotor or phase loss. It trips the control circuit to cut off power supply and prevent permanent damage to electric motors. With IP20 protection rating, it is widely used for new electrical cabinet assembly and MRO spare parts replacement in global industrial motor control systems.

✨ Product Advantages

✅ Reliable Thermal Overload & Phase Loss Protection Built-in bimetallic strip sensing mechanism. It triggers timely trip under overload and phase imbalance conditions to safeguard motors against burnout.

✅ Adjustable Current Setting Range Continuous current adjustment, flexible matching for different motor rated current, no need to replace relay for minor motor specification changes.

✅ IP20 Protection Grade Finger-safe enclosure, prevents accidental touch of live internal parts, suitable for installation inside standard electrical cabinets.

✅ Dual Contact Configuration Equipped with 1 NO + 1 NC auxiliary contacts. The NC contact is for trip interlock; NO contact can connect alarm signal for remote fault notification.

✅ Easy Contactor Mounting Direct clip-on assembly compatible with Schneider LC1D series contactors. Simple wiring and fast on-site installation, saves cabinet space.

✅ Reset Modes Available Supports manual reset by default, optional automatic reset mode after cooling down, meets different site safety operation requirements.
