What is the difference between the relay and the contactor, what is the difference
Relay load current and coil current are relatively small, the general common relay contact current capacity of 5 ~ 50A or so, used as a control loop, as the issue of electrical signals and the implementation of the part. The most common number of plug-in relays and intermediate relays, the body is relatively small.
Contactor is the load capacity is much stronger than the relay, and its contacts through the current capacity of dozens to hundreds of Bian less, mainly with the load the main line of the implementation of the line with the overload protection thermal relay series used in combination, Big.
Relays and contactors are all relay electrical components, by name, that is, through them can be interrupted, the circuit circuit in order to achieve the purpose of control circuit work. Its characteristics are small current control of high current, can pass through, off the line, high efficiency.
