TeSys LR9G

TeSys LR9G – Premium Electronic Motor Protection from Schneider Electric

At AGM Electrical Supplies, we bring you the TeSys LR9G series, which is a high-performance electronic thermal overload relay range that delivers advanced motor protection and control. Ideal for heavy-duty applications, these relays bring precision, flexibility and modern connectivity into the heart of your control panel setup.

Wide-Range Protection for Critical Motors

The TeSys LR9G electronic overload relays cover broad current ranges — for instance models span from 57–225 A in one initiative.Others extend further to 125–500 A and beyond. These broad ranges mean fewer part variations and smarter stocking for panel builders, while still providing reliable overload protection for large motors in industrial settings.

Advanced Fault Detection & Built-In Diagnostics

One of the standout features of the LR9G series is its built-in protection functions. These relays monitor for phase imbalance, phase loss, ground-faults, and single-phase loads — all within the same unit. Push-in control-connections make wiring easier and reduce installation time. Visible LED indicators provide status and trip signals right on the device, helping maintenance teams identify faults quickly.

Precision Trip Classes & Environmental Tolerance

The LR9G series supports selectable thermal overload classes from 5E to 30E, allowing you to match response speed to the type of load (e.g., high-inertia motors vs light loads). Designed to operate in challenging environments, models are rated to work from -25 °C up to 60 °C without derating, and up to 3000 m altitude.

Modular Design & Compatibility

The TeSys LR9G relays pair seamlessly with TeSys Giga contactors, allowing direct mounting or independent configuration. The push-in terminal design supports multiple conductor types and makes wiring more efficient. The modular architecture also means you can add accessories such as bus-bar adaptors or auxiliary contacts without replacing the base device.
