Schneider EasyPact TVS Thermal Overload Relay LRE363

Schneider EasyPact TVS Thermal Overload Relay LRE363

Reliable Three-Phase Motor Protection for Industrial Applications

The Schneider EasyPact TVS Thermal Overload Relay LRE363 is a high-quality differential thermal overload protection device engineered to safeguard medium-power three-phase motors against prolonged overcurrent, phase loss, and unbalanced load conditions. Designed as part of Schneider Electric’s EasyPact TVS protection range, this thermal overload relay offers dependable performance, easy installation, and robust safety — ideal for motor control setups in industrial and commercial electrical systems across India.

🔌 What Is the LRE363 Thermal Overload Relay?

The LRE363 is a three-pole differential thermal overload relay with an adjustable current setting range of 63 – 80 A. It continuously monitors current across all three phases and disconnects the motor circuit when prolonged overloads or abnormal phase conditions occur, helping prevent motor damage and reduce unplanned downtime. Designed to conform with IEC 60947-4-1 Class 10A tripping characteristics, it balances tolerance for normal motor start-up inrush with reliable overload response.

This relay can be directly mounted under compatible EasyPact TVS contactors (such as LC1E80–LC1E95) — simplifying control panel layouts and minimizing wiring complexity.

🛠️ Key Features & Benefits

• Adjustable Current Range (63 – 80 A): Tailor protection precisely to the motor’s full-load current for accurate overload safeguarding.

• Class 10A Tripping Curve: Follows IEC standards for motor protection, tolerating start-up surges while reliably tripping during sustained overloads.

• Three-Pole Differential Protection: Monitors all phases for overload, phase loss, and unbalanced conditions to enhance motor safety.

• Manual & Automatic Reset: Offers flexibility to reset automatically or manually after a trip, based on installation needs.

• Auxiliary Contacts (1NO + 1NC): Includes signalling outputs for connection to control panels, alarms, or automation systems.

• Trip Indicator Flag: Visual indication of trip status helps with quick diagnostics and maintenance.

• Screw-Clamp Terminals: Provides secure, vibration-resistant connections for both power and control wiring.

• Compact Industrial Design: Suitable for direct mounting on EasyPact TVS contactors or separate panel integration.
