Product Specification Magnetic Contractors

Magnetic contactor is an electric switch that works on the principle of electromagnetic induction. The principle works in a magnetic contactor coils there will be a magnet when in aliri electricity, the magnet will attract the contacts that are nearby so the cash which was originally open (NO) contact will be closed while the initially closed (NC) will be open. Magnetic contactors consists of the main contacts and auxiliary box. The main contact is used for a source of electric current while the auxiliary contacts are used for the control circuit. Suppose you install a second inverted in this contact magnetic contactor will continue to be able to work but there will be problems that arise because of auxiliary contacts are designed to pass only a small current while the main contacts are designed to pass large currents. If you are upside down in the installation will cause the heat because the conductor is not capable of delivering large electric current. The use of magnetic contactor is typically used to control 3-phase motor work, with the magnetic contactor we can cut 3 power sources R, S and T at the same time at 3-phase motors. To complement the usual magnetic contactor will be equipped with TOR (thermal overload relay), which serves to secure the motor what happens when excessive current. As for securing the magnetic circuit contactor will be equipped with MCB to make it more secure than short circuit.

The function of the magnetic contactor
From the description above can be concluded that the magnetic contactor is an electrical appliance such as an electric switch that serves as motor controllers and other electrical components. With the magnetic contactor installed components will be easier to control than using the ordinary switch.
