DOL Motor Starter Wiring Diagram Template

Open an editable direct-on-line motor starter template with start/stop control, contactor seal-in, overload protection, and a running indicator.

What the template contains

• Three-phase supply and motor
• Main contactor with auxiliary holding contact
• Normally closed stop and normally open start pushbuttons
• Thermal overload contact
• Running pilot light

Best used for

• Small three-phase motors that may start at full line voltage
• Training and review of a basic three-wire control circuit
• Starting a motor-control drawing before selecting exact hardware

Checks before issue

• Match control voltage to the contactor coil and pilot light.
• Coordinate motor protection, short-circuit protection, overload settings, conductor size, and isolation.
• Verify auxiliary-contact and overload terminal numbers against the ordered devices.

Engineering boundary

This starter is an editable teaching and documentation baseline, not a manufacturer-certified or installation-ready design. Motor data, fault level, duty, local code, and the selected protective devices govern the issued circuit.

Open this template in the editor. Confirm the electrical design, ratings, terminals, protection, and applicable standards before construction.
