Schneider Electric LR1-D09306 Relay

Schneider Electric TeSys LR1-D09306 is a three-pole thermal overload relay in the LR1‑D family, designed to provide motor protection when used with Schneider Electric motor control devices such as LC1D/LR1D contactors. It offers an adjustable current-setting range of 1.00 to 1.60 amperes, allowing precise trip-point tuning to the motor’s full-load current. The relay is rated for AC operation up to 660 V and 50/60 Hz, and is commonly selected for motor circuits up to about 45 kW (depending on rating and supply conditions). The LR1‑D09306 model identifies the 1.00–1.60 A setting within the LR1‑D line for reliable overload protection in three‑phase systems. This device is designed to be installed as part of a TeSys protection package behind the corresponding contactor, providing automatic overload protection for three‑phase motors.
