 DOL Starter With Timer | Motor Auto ON-OFF Wiring Diagram

Sometimes known as an 'across the line' starter,  this type of motor controller is used as a simple starter for larger electric motors, providing full line voltage to the motor terminals.

Why do we use DOL starter?

To prevent damage to the windings due to the high starting current flow, we employ different types of starters. The simplest form of motor starter for the induction motor is the Direct On Line starter.

The DOL starter consist a MCCB or Circuit Breaker, Contactor and an overload relay for protection.

2nd  Theory.   A Direct On Line (DOL) or across the line

starter applies the full line voltage to the motor terminals. This is the simplest type of motor starter. A DOL motor starter also has protection devices and, in some cases, condition monitoring.


How many types of starters are there?

The two main types of starters are Manual Starters and AC Magnetic Motor Starters, commonly known as Motor Starters. The manual starter is operated

manually.


What is the purpose of DOL starter?

A direct on line (DOL) or across the line starter applies the full line voltage to the motor terminals, the starters or cubicle locations, can usually be found on an ELO drawing. This is the simplest type

of motor starter. A DOL motor starter also contains protection devices, and in some cases, condition monitoring.
