Schneider EasyPact TVS Thermal Overload Relay LRE482

Schneider EasyPact TVS Thermal Overload Relay LRE482 — Heavy-Duty 84–135 A Motor Protection

The Schneider EasyPact TVS Thermal Overload Relay LRE482 is a premium industrial motor protection device from Schneider Electric’s EasyPact TVS series, engineered for robust and dependable protection of medium to high-capacity three-phase motors. Designed to handle demanding industrial conditions, this relay safeguards motors and electrical systems from prolonged overload, phase loss, and unbalanced current conditions — making it ideal for control panels, starter assemblies, and manufacturing installations across India.

🔌 What Is the LRE482 Thermal Overload Relay?

The LRE482 is a three-pole differential thermal overload relay with an adjustable current protection range of approximately 84 – 135 A, designed for larger three-phase motor circuits and heavy machinery. It continuously monitors current in all three phases and disconnects the circuit when sustained overloads or abnormal phase conditions occur, helping prevent motor overheating, insulation damage, and costly downtime. This relay conforms to IEC 60947-4-1 Class 10A tripping standards — balancing tolerance for normal motor start-up surge currents with reliable overload protection.

🛠️ Key Features & Benefits

• Wide Adjustable Current Range (≈ 84–135 A): Fine-tune overload protection to suit medium- and high-capacity motors.

• Three-Pole Differential Protection: Continuously monitors all three phases to detect overload, unbalance, and phase-loss conditions for comprehensive safeguarding.

• IEC 60947-4-1 Class 10A Trip Curve: Standard-compliant thermal response tolerates normal start-up while protecting against sustained overloads.

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

• Manual & Automatic Reset Options: Offers flexibility in resetting after a trip event based on installation needs.

• Trip Indicator Flag: Provides clear visual indication when the relay trips, speeding up fault diagnosis and maintenance.

• Secure Screw-Clamp Terminals: Ensures reliable, vibration-resistant wiring for both power and control circuits.

• Robust Industrial-Grade Build: Designed to withstand tough environments and provide long service life in heavy-use installations.
