Electrical Standards Direct Online (DOL) Starter

May 3, 2021 by Electrical4U Contents What is DOL Starter? A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals. The Direct On Line Motor Starter (DOL) consist a MCCB or Circuit Breaker, Contactor and an overload relay for protection. Electromagnetic contactor which can be opened by the thermal overload relay under fault conditions.

What is Direct Online (DOL) Starter? DOL Starter (Direct Online Starter) is also knows as "across the line starter". DOL starter is a device consist of main contactor, protective devices and overload relay which is used for motor starting operations. It is used for low rating usually below 5HP motors. Direct online starter is a method of starting an induction motor. The stator of the motor receives the full supply voltage in the DOL starter. Therefore, a Direct Online Starter is suitable for starting the small rating three-phase induction motors. We will also discuss the DOL power circuit diagram. A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly.

DOL starter control circuit consists of a start push button generally green, a stop push button red, a power contactor, a bimetallic overload relay, and indication lamps. The control circuit wiring diagram is shown in the below diagram In the above three phase dol starter wiring diagram. All connection i shown with complete guide. The 3 phase incoming supply shown (L1, L2, L3). The three phase supply is connected the MCCB circuit breaker. From where we can switch off the incoming supply to the direct online starter. From the MCCB the 3 phase supply goes to the contactor main. A Dol Starter, also known as a Direct On Line Starter, is an essential device used to start electric motors. It provides a reliable way of powering up machines with minimal current consumption. With this article, you will understand how it works and why it is important to have a control wiring diagram of a Dol Starter in place.

Step 3: Control Circuit Connections. Connect the control circuit wiring to the DOL starter as shown in the wiring and control diagram. to do so, Connect the digital timer's to 230V CB (usually labeled 1 & 2) and control wires to the appropriate terminals on the DOL starter as follow. 5-NO to the NO 1 - ON button and NO -13 and A1 terminal. DOL Starter is the simplest and cheapest method used for starting a three-phase induction motor. Direct online starter is used for up to 5 HP motors. this starter is more popular due to the low price. The Dol starter diagram and control wiring must be wired up correctly in order for the motor to run safely and efficiently. The diagram essentially consists of two parts: the power supply side and the control side. On the power supply side, the incoming power supply is connected to the contactor via the circuit breaker. The DOL and RDOL are motor starters used to control the power supply to the motor. The DOL starter controls the motor power ON or OFF and motor rotates in one direction only whereas the RDOL starter can make the motor to rotate in clockwise and anti-clockwise directions with two START buttons and one STOP button.
