Schneider Electric TeSyS LR Thermal Overload Relay, 4 - 6A FLC, 6A Contact Rating, 2.2 kW, 1 NO/1 NC, DIN Rail LR3D10

The Schneider Electric LR3D10 is a high-quality thermal overload relay engineered for industrial motor protection, specifically designed to safeguard motors against overload and phase failure conditions. This relay features an adjustable full load current (FLC) range of 4 to 6A, making it suitable for a wide variety of three-phase motor applications across manufacturing, HVAC control, pumping stations, and processing machinery.

With a 2.2 kW power rating and rated for 6A contact current, the LR3D10 integrates seamlessly into DIN rail-mounted control panels. The device offers one normally open (NO) and one normally closed (NC) auxiliary contact, simplifying circuit integration and ensuring both switching and monitoring flexibility. The screw terminal design ensures robust and reliable electrical connections, essential for operational dependability in demanding industrial environments.

For ease of use, this relay is equipped with a push-button reset mechanism, allowing for quick recovery after tripping. The IP20 rating provides protection against finger and tool access, supporting safe in-panel installation. The unit is certified to a wide array of standards including EAC, DNV GL, CSA, CCC, BV, ATEX, EN 50495, EN/IEC 60947, IEC, LROS, and RINA, attesting to its reliability in global commercial and industrial settings.

The LR3D10 relay can operate across a broad ambient temperature range from -20°C up to +60°C, supporting year-round use in factories, workshop environments, and automation enclosures. Its supply and contact voltage capabilities of up to 690V AC further reinforce suitability for heavy-duty electric motor control and protection, especially in high-voltage power distribution systems.

Applications of this overload relay include industrial motor starters, automatic protection panels, HVAC electrical systems, conveyor drives, material handling, and general purpose automation solutions. The three-pole relay configuration with two auxiliary contacts allows dependable signaling and control integration for machines or processes requiring motor shutdown during overload conditions.

Schneider Electric relays are trusted globally for their robust construction, safety features, and proven long-term reliability. The LR3D10 is an ideal protection solution for critical industrial motor assets, offering easy installation, precise control, and consistent fault detection.
