Schneider Electric LRE04 LRE Series 0.40-0.63A Easy TeSys Protect Thermal Overload Relay

The Schneider Electric LRE04 is an Easy TeSys Protect series thermal overload relay rated for 0.40–0.63A, designed to deliver reliable motor protection against overload and phase-loss conditions in industrial control panels and automation systems. Part of the LRE model range, the LRE04 provides adjustable trip current settings within its rated band, enabling precise protection for small motors and pumps. Weighing just 0.13 kg, this compact relay is well suited for space-constrained enclosures and high-density panel builds.

Technical Specifications

Applications & Use Cases

• Motor Protection: Safeguards small three-phase and single-phase motors against sustained overload currents that cause winding damage.
• Control Panel Integration: Mounts directly onto TeSys contactors or DIN rail, minimising wiring and panel footprint in industrial automation cabinets.
• Pump & Fan Control: Protects fractional-horsepower pump and fan motors common in HVAC, water treatment, and process industries.
• OEM Machine Building: Compact size and low weight make the LRE04 ideal for integrating into original equipment manufacturer (OEM) machine assemblies requiring reliable overload protection.
