LRD3363
Schneider Electric LRD3363 TeSys Deca thermal overload relay 63-80A Class 10A. The Schneider Electric LRD3363 is a TeSys Deca thermal overload relay providing essential motor protection against sustained overloads and phase failure. This differential relay features an adjustable thermal protection range of 63 to 80 Amperes, Class 10A, ensuring rapid and reliable tripping. It is compatible with LC1D80 and LC1D95 contactors, offering flexible mounting options (plate, rail, or under contactor). Supporting AC and DC networks from 0 to 400 Hz and rated for operational voltages up to 1000V AC, the LRD3363 includes 1 NO + 1 NC auxiliary contacts and an IP20 protection rating. This Schneider Electric relay is crucial for motor control in demanding industrial environments across Egypt and the Gulf, including cement, oil and gas, water treatment, food and beverage, textiles, and building services.
