DIRECT START
The direct start system is perhaps the simplest and most traditional and consists of connecting the engine directly to the mains supply, thus performing a full-voltage start.
It is often abbreviated to DOL (Direct On Line).
Direct starting is the simplest and most economical way to start electric pumps or motors and is the one traditionally used most.
They are suitable for starting small submersible pumps or submersible pumps or for pressure boosting systems with
surface pumps.
The switchgear provides a direct connection to the mains, which implies:
- Starting at full voltage and constant frequency
- High starting torque
- Very short average acceleration times.

CARATTERISTICHE CHIAVE
Components
DIRECTO control panels are manufactured in plastic or metal enclosures with a minimum protection rating of IP55.
Each switchboard has warning lights for voltage presence, thermal intervention and motor in operation, a manual or automatic selector switch, a disconnector switch with door lock system.
A terminal board allows connection to external utilities and controls such as pressure switches, floats, etc.
Applications
Direct starting is the simplest and most economical way to start electric pumps or motors, and is traditionally the most widely used. The current induced in the rotor is high. This results in a peak current on the mains which can be 5 to 8 times the rated current. They are suitable for starting small submersible pumps or for pressure boosting systems with surface pumps.
