LRD03
Schneider Electric LRD03 TeSys Thermal Overload Relay 0.25-0.4A Class 10A. The Schneider Electric LRD03 is a robust TeSys LRD thermal overload relay, meticulously engineered for reliable motor protection against sustained overload conditions. This essential device features a precise thermal protection adjustment range of 0.25 to 0.4 A, making it ideal for safeguarding smaller motors. Conforming to Class 10A according to IEC 60947-4-1, the LRD03 ensures quick and effective tripping in overload situations. It supports both AC and DC network types, with a rated operational voltage of 690 V AC (0-400 Hz) for the power circuit, and includes 1 NO + 1 NC auxiliary contacts for versatile control circuit integration. With an IP20 degree of protection and an ambient operating temperature range of -20 to 60 °C, the Schneider Electric LRD03 is built for durability in demanding industrial environments. Its compact dimensions (66 mm H x 45 mm W x 70 mm D) and various mounting options (plate, rail, under contactor) allow for flexible installation. Compatible with TeSys D contactors like LC1D09 through LC1D38, this relay is a perfect fit for motor control applications in critical sectors across Egypt and the Gulf, including water treatment, oil and gas, food and beverage, cement, textiles, and building services.
