Schneider EasyPact TVS Thermal Overload Relay LRE12

Schneider EasyPact TVS Thermal Overload Relay LRE12 — 5.5–8 A Motor Protection

The Schneider EasyPact TVS Thermal Overload Relay LRE12 is a compact and reliable three-phase motor protection device from Schneider Electric’s EasyPact TVS series. Designed to prevent damage from prolonged overload, phase loss, and unbalanced load conditions, this relay delivers dependable performance and compliance with international motor protection standards — ideal for industrial, commercial, and workshop electrical systems in India.

🔌 What Is the LRE12 Thermal Overload Relay?

The LRE12 is a three-pole differential thermal overload relay with an adjustable current protection range of 5.5 – 8 A, making it suitable for safeguarding small three-phase motors used in pumps, fans, conveyors, and light industrial equipment. It continuously monitors current in all three phases and disconnects the motor circuit during sustained overloads or abnormal phase conditions — protecting your motor from overheating and premature failure.

Built to meet IEC 60947-4-1 Class 10A tripping standards, the LRE12 balances tolerance for normal start-up current surges with reliable overload response. It also supports direct mounting under compatible EasyPact TVS contactors (e.g., LC1E09…LC1E38) to reduce wiring complexity and save panel space.
