Direct Online Starter (DOL)

The most common for small direct on-line starters (DOLs) is 415VAC,
as this requires no natural to be fed to the starter.
Option are also given for using either a remote stop switch or for
using the stop button which in integral with the overload. In the
latter case the stop button is not a switch, it is a plunger type device
filled into the lid/door of the enclosure, which will physically press
the overload stop. This is the method that is used in the Schneider
electronic tesys enclosed motor starters, such as the tesys LE range
or the tesys LE1GB***range.
