All of T-T's standard DOL/ASD Controls Panels are manufactured on-site and undergo rigorous testing to ensure that they meet our high standards, with bespoke options available so that you receive optimal performance for your application.
Direct On Line (DOL) start is the most simple motor start option, Direct on Line (DOL) starting directly connects an induction motor to a 3-Ph power supply with the addition of a contactor and an overload relay, providing overload protection.
DOL start is the simplest and most cost-effective system for starting pumps and motors and it is traditionally the most widely used. The induced current is the rotor is high. This results on a peak current on the network which can be 5 to 8 times the nominal current.
They are suitable for startup of small submersible pumps, deep well pumps or booster sets with surface pumps.
DOL control panels need a direct connection to the power supply network, which implies:
