Types of Motor Starters
There are several types of motor starters. However, the two most basic types of these
electrical devices are:
1. Manual Starters
Manual starters are devices that are operated manually. These starters are extremely
easy and straightforward to operate and do not require expert intervention. The
starter includes a button (or rotary knob) which enables a user to turn the connected
equipment on or off. The buttons features mechanical linkages, which make the
contacts open or close, starting or stopping the motor. The following features of a
manual starter make it a preferred choice over other types:
• These starters deliver a safe, as well as economical operation.
• The compact size of these devices make them suitable for a wide range of
applications.
• They provide overload protection to the motor, protecting it from any potential
damage.
• These devices come with a vast choice of enclosures.
• The initial cost of the manual starter is low.
