Get to know the contactor working system and its functions
Navigation Info - Contactor (Contactor) is an electrical component or spare part that functions to disconnect and connect electric currents by utilizing an electric magnetic field or better known as an electromagnetic field.
|Get to know the contactor working system and its functions|
Electromagnetic field itself is magnetic energy produced by an electric field (electric current) passing through a metal / conductor that affects a vector space (magnetic field room) by making a cable winding which is given an electric current, the room in the middle and around the coil will become an electric magnetic field.
The electric current will pass through the coil and produce two energies, namely magnetic energy and heat energy. the heat generated from the magnetic field does not damage the contactor.
In another meaning of choosing a quality electrical contactor can improve the durability or durability of your industrial machines due to the calculation of the manufacture and the quality of the material is guaranteed.
Because not infrequently I also meet in the field some of the contactors used are counterfeit goods (KW) which make the production machine easily damaged and the damage spreads to other electrical components or spare parts.
Contactor component parts
The contactor itself consists of the following components:
1. Contactor coil
The most important part of the contactor is the contactor's electric coil which functions converts electrical energy into magnetic energy by providing current at both poles.
The coil itself is in the form of a coil of copper wire located at the bottom of the contactor which will later generate magnetic energy and make the contactor work or operate.

2. Normaly Open ( NO ) contactor
NO ( normaly Open ) is a connector found on the contactor if you tester with a multi tester or ohm meter when the contactor coil is not given an electric current then NO will be in the unconnected position.
Meanwhile, when the contactor coil is given an electric current, the NO will be attracted by the magnetic field generated by the contactor coil so that the NO contactor connector will be connected.
3. Normaly Close ( NC ) Contactor
NC ( normally Close ) is a connector on the contactor is the same as NO but when the contactor coil is not given an electric current then the NC connector if you tester using an ohm meter or multi tester then the NC connector will be connected.
And vice versa if the contactor coil is given an electric current then the NC connector if you test using an ohm meter or multi tester then. NC connector disconnected.
Contactor working system
As explained above that Sanya contactor consists of 3 types of parts, namely coil contactor, NC connector and NO connector .
Which when the electric current is connected with the contactor coil, the contactor coil produces a magnetic field that will attract the NC and NO contactors so that the electric current contained in the NC connector will be cut off and vice versa on the NO contactor connector will connect the electric current.
With this working system, we can vary or modify the electrical circuit design according to what we need and want.
