Modular design: LC1-N Type AC Contactor adopts modular design with complete function combination, which is convenient for users to choose and combine according to their needs.
Electromagnetic system: including electromagnetic coil and iron core, which is an important part of the contactor, relying on it to drive the closure and disconnection of contacts.
Contact system: including main contact and auxiliary contact. The main contact is used to connect and break the main circuit and control the larger current; the auxiliary contact is in the control circuit to meet the requirements of various control methods.
Arc extinguishing system: equipped with an arc extinguishing device, generally semi-closed longitudinal slit clay arc extinguishing cover, and equipped with a strong magnetic blowing arc circuit to ensure that the contacts to break the circuit generated by the arc is reliably quenched, reduce the arc damage to the contacts.
When the control circuit is energized, the electromagnetic coil generates a magnetic field, which attracts the iron core to drive the contacts to close, thus connecting the main circuit of the compressor. When the control circuit is de-energized, the magnetic field disappears, the iron core is reset under the action of the spring, the contact is disconnected, and the main circuit of the compressor is also disconnected.
Rated control power supply voltage: including 24V, 48V, 110V, 127V, 220V, 240V, 380V, 415V, 440V, 480V, 500V, 600V, 660V and other options.
Suction voltage: usually (0.85~1.1) times the rated control supply voltage.
Release voltage: usually (0.2~0.75) times the rated control supply voltage.
Suction time: Depending on the model, the suction time varies, usually between 12~35ms.
Release time: Again, the release time varies depending on the model, generally between 4~20ms.
Electrical life: In the AC-3 use category, the electrical life can be hundreds of thousands of times to millions of times.
Mechanical Life: Mechanical life is typically in the range of millions to 10 million cycles.
