Contactor Chint NXC series - Good price, high quality, genuine

Construction - Specifications - Starting from  NXC Chint Series

In electrical control systems, the magnetic starter is an extremely important and widely used device. So how are they structured? How does it work? Let's find out with Amazen whether a NXC Series starter from Chint is similar to another type of starter through the article below!

1. What is a starter? Starts from the NXC Chint Series

- Magnetic starter, also known as Contactor or contactor in Vietnamese parlance, is a particularly important low-voltage electrical device in electrical systems. It is responsible for performing regular closing and cutting of electrodynamic circuits.
- Contactor – Magnetic starter is an intermediate electrical switching device widely used in the field of electrical control of electrical equipment, playing an important and indispensable role in electrical control systems of all types of machinery and equipment. When using a contactor (magnetic starter), we can apply electrical switching with remote power circuits for most types of loads such as electric motors, lighting systems, capacitors, specialized machinery... By controlling by supplying power to the suction coil (the coil inside the contactor creates a suction force to close the main contacts), the devices in the system are switched on and off safely and easily operated with accessories. such as buttons, lever switches...

- Contactors are divided into AC contactors (alternating voltage) and DC contactors (direct current voltage), used in power supply, distribution and control power. The contactor is used to control the main circuit on and off through the control coil. Contactors come in a full range of types, including air type, vacuum type, module type, capacitive type,...

- NXC Series Chint magnetic starters have novel characteristics and compact structure, they are mainly used for starting and controlling AC motors as well as remotely closing /breaking circuits and can also be combined with other Thermal relays are suitable for creating electromagnetic starters.

2. Structure of magnetic starter

Magnetic starter has three main parts including: Electromagnet, contact system and arc extinguishing system.

Starting structure
- Electromagnet: includes an iron core, a spring to push the lid core back to its original position, and a coil to create magnetic attraction. The function of a magnet is to create a magnetic field.
- Contact system: includes main contact and auxiliary contact:
 + Main contact: is a normally open contact, will close when power is applied to the magnetic circuit of the magnetic starter in the electrical cabinet, making the magnetic circuit suction again. A contact capable of allowing large currents to pass through.
 + Auxiliary contact: Auxiliary contact has 2 states: normally closed and normally open. A contact capable of allowing current through the contacts to be less than 5A.
- Arc extinguishing system: Due to continuous switching, an electric arc will appear, causing the contacts to burn and gradually wear out, so an arc extinguishing system is needed.

7. Application of NXC Series magnetic starter

- Used for motor control in industry and civil use
- Used to switch on and off power sources in Industry, civil, construction...
- Contactor Chint is widely used in factories assembling electronic components, packaging and processing food, weaving and garments, assembling cars... Specifically:
+ Star-delta starting contactor helps switch starting mode from star to delta when the motor is stable, helping to reduce starting current.
+ Motor control contactor: It not only supplies power to the starting motor directly, but it also combines with a relay to protect against overload.
+ Lighting control contactor: People will use a combination of PLC or time relay to turn on and off the power supply to the light bulb system according to the specified time. It is widely used in airport, park, and dock lighting systems.
+ Capacitor control contactor: Its function is to compensate reactive power through switching capacitors or switching capacitor levels to suit the working load.
