Motor starter usually refers to the complete assembly, including enclosure, contactor, control transformer (if any), overloads, fuses (if any), etc. A contactor is really just an overgrown relay, and is just one component of a starter. That having been said, many folks use the two terms somewhat interchangably. So someone who says starter may mean contactor, and vise-versa. Go figure.
What else can I help you with?
What is the difference between an definite purpose contactor and a lighting sontactor?
A definite purpose contactor is designed (and rated) for a specific load. So a lighting contactor is one example of a definite purpose contactor. A motor starter contactor is another example. So, a lighting contactor is a definite purpose contactor, but a definite purpose contactor is not necessarily a lighting contactor (it might be a motor starter, for instance).
What are magnetic shading coils and what do they do in a magnetic motor Starter?
Shading coils provide a phase shift between the magnetic field of the rotor and stator, which is necessary to get the motor spinning.
How do you wire up a 208v single phase motor with micro switch?
if you are using the pressure switch to control a 3phase pump chances are it already has a magnetic starter and a single pole control circuit i have seen small 3phase air compressors with the contacts driven right off the diaphragm bigger ones usually have 110 volt controls i would be concerned about the current rating of the switch if you are trying to switch the motor directly there are many single phase compressors that run directly from the pressure switch
Are contactor points and bimetallic strip connected to the star delta starter of 3 phase induction motor?
yes
What is the difference between dol and hdol?
Direct on line starter and Heavy direct on line starter...... in HDOL CT is fixed.
What is the difference between a motor starter and a contactor?
Motor started will have overloads the contactor connect es line voltage.

What is magnetic line voltage motor starter?
A motor starter is a contactor (heavy duty relay) which acts as a remote-controlled on/off switch between the supply and the motor. Its operating coil is energised through an auxiliary stop/start circuit. It also incorporates overload function which will automatically disconnect the motor in the event of a sustained overload current.
Can 125v magnetic switch be used in 12v system?
If what you term as a "magnetic switch" is an electrical contactor, then the answer is yes.A couple things to keep in mind. I presume the 125 volts mentioned is the coil voltage of the contactor.The switched voltages and amperage or horsepower allowed by the contactor is on the contactor's nameplate. This is the maximum voltage that can be applied to the contactor which includes 12 volts.The amperage of the 12 volt device is not mentioned and this should not exceed the maximum allowed current of the lowest voltage rating of the contactor. This is especially true if the 12 volts is Direct Current. An example of this could be a starter on a car. When the starter starts to crank it could be in the neighbourhood of 300 amps DC. As you can see this would fry the contacts of a normal AC rated contactor.
What is the difference in between mata and a soup?
Soup is a starter
What is the difference between a Y - delta starter and a star - delta starter?
No difference. Y is used as a symbol to indicate the star connection.
What are magnetic shading coils and what do they do in a magnetic motor Starter?
Shading coils provide a phase shift between the magnetic field of the rotor and stator, which is necessary to get the motor spinning.
What components can be changed on a contactor and a starter for rebuilding purposes?
Various components can be added and removed from a contactor. Auxiliary contacts can be inserted in front of the main contacts, as well as a time relay in the case of motor starters (star/delta starter). Usually you should fit a overload relay when you use the contactor in a motor starter, this is inserted in the main contacts at the bottom. However, the internal components like the coil may never be changed or replaced.
