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.
What are the parts of the magnetic contactors?
A contactor consists of three basic parts: the operating coil, the associated magnetic circuit and the contacts that are actuated by the coil.
What does the term magnetic refer to when talking about contactors?
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.
What is a magnetic contactor used for?
Magnetic contactors are the same as the electrical relays which are used in a number of electric motors. Magnetic contactors are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from ON and OFF state.
What is the best magnetic conductor?
Some of the best metallic conductors are copper (Cu), silver (Ag), and gold (Au). (2) There are some conductors that are not metals. Carbon is the best example.
What is a magnetic contactors?
Why do we use 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 the purpose of a magnetic contactor?
What is the difference between a contactor and a relay?
A contactor joins 2 poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. Additionally, contactors are commonly rated for up to 1000V, while relays are usually rated to only 250V.
How does a magnetic contactor work on a motor?
This is an auxiliary contact unit with low level contact, capable of opening and closing the low voltage and minute current of the electronic control circuit. It can be installed with one touch onto the magnetic contactor or magnetic relay that opens and closes the power of the motor, etc.
Which is Te main contactor for high voltage?
The new EVC 175 main contactor expands TE’s high voltage contactors portfolio. The EVC 175 is a compact, high voltage, main contactor for use in hybrid and electric vehicle applications in the medium power range.
Can a microswitch be used for a low level magnetic contactor?
A compact microswitch is used for the low level contact, so the unit will not malfunction due to fields and surge voltages from the main circuit current and coil of the magnetic contactor. A 1NO+1NC low level contacts and 1NO+1NC standard contacts are built-in, so the opening and closing of 200VAC and 24VDC can be handled with one unit.
What are the contactors in an electric vehicle?
Electric Vehicle (EV) Contactors primarily act as the main contactors in electric vehicle drive circuits in all sizeable electric vehicles: cars, trucks, boats and rail locomotives. high current short circuit, might occur, resulting in a fire.
