LR3D086

Schneider Electric LR3D086 – reliable thermal overload relay for motor protection
The Schneider Electric LR3D086 is a high-performance thermal overload relay from the TeSys LRD range. With an adjustable current setting from 2.5 to 4 A, and a trip classification of class 10A, it is designed to protect three-phase motors from overloads, phase-failure, long starting times and stall conditions. It is suitable for use in circuits up to 690 V AC and supports unbalanced loads.
Key features and benefits

• Adjustable current range 2.5-4 A supports flexible motor rating configurations.

• Class 10A trip characteristic ensures effective protection for standard industrial motors.

• Designed for 3-phase motor protection including overload and phase loss scenarios.

• Compact and easy to install beneath compatible contactors or on DIN-rail, offering space-efficient integration.
  Where is the Schneider Electric LR3D086 used?
  This thermal overload relay is commonly applied in industrial control panels and motor starter circuits, for example:

• Three-phase motor starters in manufacturing equipment requiring reliable overload protection.

• Compressor, pump and fan systems in HVAC and process automation where phase-imbalance or motor stalling may occur.

• Retrofitting older motor control centres where modern adjustable relay protection is needed.
