Feature: 1. PC Flame Retardant Shell: The shell of the contactor is made of PC flame retardant material, which is high temperature resistant, flame retardant and durable for a longer time. 2. Strong Loading Capacity: The contactor has a sufficient amount of copper core coil, strong resistance, superior performance and strong loading capacity. 3. High Silver Contact Content: The contactor has high silver contact content, which improves the electrical conductivity and makes it more sensitive to load larger currents. 4. Retrofit Reorganization: The contactor can also be retrofitted with auxiliary contact sets, air delay heads, mechanical interlocks and other accessories to form time delay contactors and so on. 5. Widely Used: The contactor is suitable for AC 50Hz or 60Hz, for long distance connection and breaking of circuits and frequent starting and control of AC motors. 6. Protection Function: The contactor can be installed directly with the thermal relay to form an electromagnetic starter to defend the circuit of overload.
