Schneider EasyPact TVS Thermal Overload Relay LRE353

Schneider EasyPact TVS Thermal Overload Relay LRE353 — 23–32 A Motor Protection Relay

The Schneider EasyPact TVS Thermal Overload Relay LRE353 is a reliable motor protection device from Schneider Electric’s trusted EasyPact TVS series. Designed to offer dependable three-phase motor overload protection, this relay helps prevent motor overheating, phase loss, and unbalanced load conditions — making it a practical choice for industrial, commercial, and workshop electrical systems across India.

🔌 What Is the LRE353 Thermal Overload Relay?

The LRE353 is a three-pole differential thermal overload relay with an adjustable current protection range of 23 – 32 A. It monitors current in all three phases of a motor circuit and disconnects the circuit when sustained overloads or abnormal phase conditions are detected, reducing the risk of motor damage and costly downtime. Built to conform with IEC 60947-4-1 Class 10A tripping standards, the LRE353 balances tolerance for start-up inrush currents with reliable overload response.

This relay is designed for direct mounting with compatible EasyPact TVS contactors — simplifying panel design and installation in motor starter assemblies.

🛠️ Key Features & Benefits

• Adjustable Current Range (23 – 32 A): Allows precise tailoring of thermal protection to match motor full-load current.

• Class 10A Trip Characteristic: Provides standard-compliant overload protection while tolerating typical start-up currents.

• Three-Pole Differential Protection: Monitors all three phases to detect overload, phase loss, and imbalanced conditions efficiently.

• Manual & Automatic Reset: Offers flexibility to reset the relay automatically or manually after a trip event.

• Auxiliary Contacts (1 NO + 1 NC): Enables connection to control panels or automation systems for fault signalling.

• Trip Indicator Flag: Provides visual indication when a trip occurs, simplifying fault diagnostics.

• Secure Screw-Clamp Terminals: Ensures reliable, vibration-resistant electrical connections.

• Compact Design: Suitable for installation in motor control panels with EasyPact TVS contactors to save space.
