DC Contactor is a common electrical equipment used for controlling the current in the electrical circuit. It comes in many types and can be classified based on its working principles and structural characteristics. Let's introduce the basic characteristics and principles of DC Contactor.

1. Basic Features of DC Contactor

Working voltage: The working voltage of DC contactor is usually DC 12V, 24V, 36V, etc.
Working current: The working current of DC contactor can be from several amperes to several thousands amperes.
Control object: DC contactor can be used to control the current in the AC circuit, and also used to control the current in the DC circuit.
Auxiliary contact: The auxiliary contact of DC contactor can be used to connect and disconnect the control circuit, as well as to adjust and protect it.
Waveing device: Generally, DC Contactors are equipped with an smoothing device to effectively protect the circuit and contact parts from damage.
Service life: The service life of DC contactor is usually long, can reach several decades or even longer.

2. Working Principles of DC Contactor

The main functions of DC Contactors are connected and broken in circuits and load protection. Before the main contacts closed, the auxiliary contacts are open; only after the main contacts closed, the auxiliary contacts are closed.
