Schneider EasyPact TVS Thermal Overload Relay LRE22

Schneider EasyPact TVS Thermal Overload Relay LRE22 — 16–24 A Motor Protection

The Schneider EasyPact TVS Thermal Overload Relay LRE22 is a dependable three-phase thermal overload protection device from Schneider Electric’s EasyPact TVS series, designed to safeguard motors against prolonged overcurrent, phase loss, and unbalanced load conditions. This relay is ideal for use in motor starter panels, industrial control systems, and commercial electrical installations across India where reliable motor protection is critical.

🔌 What Is the LRE22 Thermal Overload Relay?

The LRE22 is a three-pole differential thermal overload relay with an adjustable current setting range of 16 – 24 A — suitable for protecting medium-capacity three-phase motors. It continually monitors current in all three phases and disconnects the circuit when sustained overloads or abnormal phase conditions are detected, helping to prevent overheating and damage to the motor and connected equipment.

Built to meet IEC 60947-4-1 Class 10A tripping standards, this relay balances tolerance for normal start-up current surges with dependable response to genuine overload situations. It can be directly mounted on compatible EasyPact TVS contactors (e.g., LC1E25…LC1E38), reducing wiring complexity and saving panel space.

🛠️ Key Features & Benefits

• Adjustable Current Range (16 – 24 A): Fine-tune overload protection to match the motor’s full-load current for accurate safeguarding.

• Class 10A Trip Characteristic: Designed to meet IEC standards for reliable overload response while tolerating start-up inrush currents.

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

• Auxiliary Contacts (1 NO + 1 NC): Provides signalling outputs for integration with control panels, PLCs, or alarm systems.

• Manual & Automatic Reset Options: Choose reset behaviour that suits your maintenance and safety needs.

• Trip Indicator Flag: Visual indication simplifies fault diagnostics and reduces troubleshooting time.

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

• Direct Contact Mounting: Simplifies installation on EasyPact TVS contactors or independent panel mounting, saving control panel space.
