Working principle diagram of energy storage equipment contactor

What are the contactor's main power connections?

The contactor has six main contacts for power connection, where three are fixed cores and the other three are movable cores. The contactor consists of two iron cores, where one is fixed and the other one is the movable coil and it is an insulated copper coil. Where the copper coil is located on the fixed core.

How does a contactor work?

A contactor works on the principle of electromagnetism. When current flows through the electromagnetic coil, it generates a magnetic field that attracts the moving coils. This action causes the contacts to close or open, allowing or stopping the flow of current.

What is the construction of a contactor?

The construction of a contactor mainly consists of two types of coils: AC coil and DC coil. For AC coils, options are available for 110, 240, and 415 volts, while DC coils have options for 12 and 24 volts. The mechanical life of a contactor ends when...

What voltage can a contactor operate on?

One unique quality of contactors is that their coils can be powered by both DC and AC currents. Typical voltages include 12VDC, 24VDC, and 220V AC, with the most popular being 24V DC for many control circuit applications. Contactors are primarily used for controlling single and three-phase motors and switching power circuits.

Where are contactors used?

Contactors are used in light loads, complex machine control, and other electrical power circuits. A contactor is one of the main electrical circuit parts, which can stand on its own power control device or a part of a starter. They are used to connect and break power supply lines running through power lines.

How does a contactor armature work?

When current is supplied to a contactor, the electric current excites the electromagnet, producing a magnetic field that moves the armature as shown in our schematic below. This movement causes the contactor core to open or close the contacts.
