ACROSS THE LINE MOTOR STARTERS

The simplest type of motor starter is an across the line starter or a direct on line (DOL) starter. It is also the starter that experiences the highest current during the motor starting process.

These starters apply the full line voltage to the motor terminals. A DOL motor starter oftenDOL starters contains protection devices and in some cases, it has condition monitoring. OL starters

An across the line starter can be used if the high inrush current of the motor does not cause excessive voltage drop in the supply circuit. The maximum size of a motor allowed on a direct online starter may be limited by the supply utility.

These starters are can be used with most applications such as when starting small compressors, fans, water pumps, and conveyor belts. They are also considered to be user friendly and cost-efficient.
