What are the types of magnetic contactor?

Magnetic Contactor Types

• Magnetic starter.
• Reversing starter.
• Star-Delta starter.
• Mercury contactor.
• Vacuum contactor.
• Mercury-wetted contactor.

What is magnetic contactor?

A magnetic contactor is a device that is powered by magnetism. Used to open and close the contacts in the motor control circuit, may also be called a magnetic switch or a contactor. A magnetic contactor is a device that is very often used in industry.

How do I choose a magnetic contactor?

The choice of contactor is dependant upon many parameters i.e. operating voltage, size of contacts, number of operations, ambient temperature, type of load supplied etc. Loads are categorised into various AC ratings, (AC1, AC2, AC3 etc.) and the higher the AC rating the more inductive the load becomes.

What is pre magnetic contactor?

PMC (Pre Magnetic Contactor) has Silver Points in between Copper Bars that switch very quickly and operate at 160 volt to 490 volt. PMC switch fastest because it works 24vdc coil of 3 Pole. We Use Imported Crystal Copper in Star Delta Starters. To Know More About Our products.

How many types of contactors are there?

There are two types of power contact; stationary contact and movable contact. The material used for the contacts has stable arc resistance and high welding resistance.

What are electric contactors?

A contactor is an electrical device which is used for switching an electrical circuit on or off. These contacts are in most cases normally open and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used for controlling electric motors.

What is ac2 contactor?

AC-2: These are used in slip-ring motors starters such as Switching on and switching off the motor. AC-3: These types of contactors are generally preferred for the starting of Squirrel-cage motors, and switches off motor during the running time which means the contactor can withstand high current continuously. Example.

What is contactor and types?

A contactor is an electrical device which is used for switching an electrical circuit on or off. Contactors are most commonly used for controlling electric motors. There are various types of contactors, and each type has its own set of features, capabilities, and applications.

What is magnetic relay?

Magnetic latching relay is a new type of relay developed in recent years. It is also an automatic switch. Like other electromagnetic relays, it can switch on and off the circuit automatically.

What are the different parts of a magnetic contactor?

The contact includes different contacts like power contacts, contact springs, and auxiliary contacts. The circuit of the magnetic contactor is enclosed in an insulating material like Nylon 6, thermosetting plastics and Bakelite. The circuit is enclosed for protection in case of touching.

How many types of contactors are there in power supply?

From the article, there are approximately about 14 different types of contactors, which may well have more sub-variants based on the voltage / current application. Have a better day !

What are the different types of power starter contacts?

Electric power starters are crucial components of contactors and protection relays because they provide under-voltage, power-cutoff, and overload protection. These types of contactors and protection relays include motor logic state, type S contactors, and TeSys N contactors.

What are the different types of contacts in electrical devices?

Contacts: This is yet another important component of this electrical device. The current carrying task of the contactor is done by the contacts. There are different types of contacts in a contactor namely, contact springs, auxiliary contacts, and power contacts. Each type of contact has an individual role to play.
