Schneider EasyPact TVS Thermal Overload Relay LRE322

Schneider EasyPact TVS Thermal Overload Relay LRE322 — 17–25 A Thermal Motor Protection

The Schneider EasyPact TVS Thermal Overload Relay LRE322 is a compact and reliable three-phase motor protection device from Schneider Electric’s trusted EasyPact TVS range. Designed for industrial and commercial electrical systems, this relay provides dependable thermal overload protection for three-phase motors, helping prevent damage due to prolonged overcurrent, phase loss, and unbalanced load conditions. It’s ideal for use in motor starter panels, workshops, and electrical control cabinets across India.

🔌 What Is the LRE322 Thermal Overload Relay?

The LRE322 is a three-pole differential thermal overload relay with an adjustable current protection range of 17 – 25 A — suited for protecting medium-capacity three-phase motors in industrial motor control applications. It continuously monitors current through all three phases and disconnects power when sustained overload or abnormal phase conditions occur, helping prevent motor overheating and associated failures.

Designed according to IEC 60947-4-1 Class 10A standards, the relay balances tolerance for normal motor start-up surges with reliable response against extended overload conditions. This ensures both performance and safety in demanding applications.

🛠️ Key Features & Benefits

• Adjustable Current Range (17 – 25 A): Tailor thermal protection precisely to your motor’s full-load current for efficient safeguarding.

• Three-Pole Differential Protection: Monitors all phases to detect overload, phase loss, and unbalance for comprehensive motor safety.

• Class 10A Trip Characteristic: Meets IEC standards for dependable tripping performance with tolerance for start-up inrush currents.

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

• Manual & Automatic Reset Options: Flexible reset behaviour based on operational and maintenance needs.

• Trip Indicator Flag: Visual trip status indication simplifies fault diagnostics and servicing.
