Question

why do you need to study the differences of motor starter, manual starter​

Answer 1

Answer:

here's your answer

Magnetic motor starters rely on electromagnets to close and hold contactors rather than the use of mechanical latching of on/off switches as used in manual starters. Magnetic motor starters can also be wired to restart motors automatically if the application requires it, a remote pump, for example. therefore it is important to study the difference of motor starter and manual starter.
