    50a dc contactor dimensionTips: Different Functions between contactor and relay
    Primary function of a relay is to detect, transmit, convert or dispose the signal, it's on-off current is generally small. The relay is usually used in a control circuit to control the weak signal.
    Primary function of a contactor is to connect or disconnect the main circuit. The main circuit refers to the one whose working situation is determined by the connection of this circuit. The concept of main circuit corresponds to the control circuit, generally, the current of a main circuit is larger than that of a control circuit.
    In general, a contactor with large capacity is equipped with an arc chute. The contact capacity of a relay will not exceed 5A, that of a midget relay may be 1A or 2A. However, the minimum contact capacity of a contactor could be 9A. Contacts of the contactor usually have three pairs of main contacts (the main contacts are normally open contacts), it also has several pairs of auxiliary contacts.
    However, contacts of a relay is generally not divided into main contacts or auxiliary contacts. Sometimes, contacts of a relay are set in pairs, namely the normally open contacts and normally closed contacts are combined, while that of a contactor are not in pairs. As for specific needs, the relay will combine with other equipment into a time relay, a counter or a pressure relay, which has the additional functions, but a contactor doesn't have.
