LRD3322
Schneider Electric LRD3322 TeSys Deca Thermal Overload Relay. The Schneider Electric LRD3322 is a robust TeSys Deca differential thermal overload relay, expertly engineered to provide critical motor protection against sustained overloads and phase failures. With a thermal protection adjustment range of 17-25 A and conforming to Class 10A (IEC 60947-4-1), this versatile relay supports both AC and DC network types across a wide 0-400 Hz frequency range. It boasts a high rated operational voltage of 1000 V AC for the power circuit, ensuring broad applicability. Essential for safeguarding critical motors in diverse industrial sectors across Egypt and the Gulf region, including demanding environments in oil and gas, water treatment, cement production, food and beverage processing, and textiles. The LRD3322 integrates seamlessly with LC1D80 and LC1D95 contactors, features 1 NO + 1 NC auxiliary contacts, and offers IP20 protection. Its reliable operation across an ambient temperature range of -20 to 60 °C makes it an ideal component for maintaining operational continuity.
