Schneider EasyPact TVS Thermal Overload Relay LRE361

Schneider EasyPact TVS Thermal Overload Relay LRE361 — Robust Three-Phase Motor Protection

The Schneider EasyPact TVS Thermal Overload Relay LRE361 is a reliable industrial motor protection device designed to protect medium-power three-phase motors from prolonged overcurrent, phase loss, and unbalanced load conditions. Part of Schneider Electric’s EasyPact TVS range, this differential thermal overload relay ensures accurate, standards-compliant protection and seamless integration with EasyPact TVS contactors in motor starter panels across factories, workshops, and commercial electrical systems in India.

🔌 What Is the LRE361 Thermal Overload Relay?

The LRE361 is a three-pole differential thermal overload relay with an adjustable current protection range of approximately 55 – 70 A, specifically designed for medium-capacity motor applications. It monitors current across all three phases and disconnects the motor circuit when sustained overloads or abnormal phase conditions are detected — helping prevent overheating and motor winding damage before failure occurs.

Built to meet IEC 60947-4-1 Class 10A tripping standards, the LRE361 balances tolerance for start-up current surges with dependable response to true overload situations, improving safety and equipment longevity.

🛠️ Key Features & Benefits

• Adjustable Current Protection (≈55 – 70 A): Lets you match overload settings with your motor’s full-load current for precise protection.

• Class 10A Trip Characteristic: Conforms to IEC norms for balanced overload response while tolerating normal start-up inrush.

• Three-Pole Differential Monitoring: Detects overload, phase loss, and imbalance conditions for comprehensive motor safeguarding.

• Auxiliary Contacts (1 NO + 1 NC): Supports signalling to control panels, PLCs, or automation systems.

• Manual & Automatic Reset Options: Provides flexibility based on maintenance and safety requirements.

• Trip Indicator Flag: Quick visual feedback for fault diagnostics and faster troubleshooting.

• Screw-Clamp Terminals: Ensures secure and vibration-resistant wiring.

• Direct Mounting on EasyPact TVS Contactors: Simplifies panel design and installation with minimal wiring.
