The product is mainly used in a circuit of AC 50Hz or 60Hz, rated working voltage up to 660V and rated working current up to 95A under application class of AC-3. It is used to remotely make and break the circuit. Connected with a proper thermal relay, it can form an electromagnet starter to protect a circuit in which overload running may occur, and to be used for frequent start and control of an AC motor.
Conform the standard: GB14048.4
Many derived products can be formed by mounting auxiliary contact assembly, air time delay contact, thermal relay and other accessories to the contactor in module erection mode.
