Description
The Schneider Electric (Square D) LRD08 is a thermal overload relay engineered to provide dependable motor protection in a wide range of industrial and commercial HVAC applications. Designed to mount directly onto TeSys D-series contactors, this relay delivers precise, adjustable overload protection without the need for additional wiring or mounting hardware.
Product Overview
The LRD08 features a current setting range of 2.5 to 4.0 amps, making it ideal for protecting smaller motors and loads commonly found in HVAC equipment, pumps, fans, and compressor systems. Its bimetallic thermal sensing mechanism responds to sustained overcurrent conditions, tripping the relay to prevent motor burnout and costly equipment damage.
