SCHNEIDER ELECTRIC LR9G115 - Electronic Overload Relay
The SCHNEIDER ELECTRIC LR9G115 is an electronic overload relay from the TeSys LR9G series, engineered for precise protection of three-phase AC motors against overload, phase unbalance, and phase loss. It integrates directly with TeSys D contactors, providing advanced motor control and safeguarding in industrial applications such as pumping systems, conveyor belts, and HVAC units. This device utilizes electronic sensing for enhanced accuracy and a wider current adjustment range compared to traditional thermal relays.
