10 HP DOL Starter Panel Electrical Schematic with Control Wiring

This electrical drawing provides a comprehensive documentation of a 10 HP Direct-On-Line (DOL) starter panel designed for industrial motor applications. This schematic includes front and side views of the enclosure alongside detailed control wiring diagrams. Key components include a 3-phase, 50A MCB for main power distribution, an overload relay (OLR) with setting range of 12-18A, contactor, start/stop push buttons, and indicator lights for ON/TRIP/OFF status monitoring. The panel features R-Y-B phase indicators and incorporates a 4″×4″ cooling fan powered by a separate 2P, 6A MCB for thermal management. The control circuit shows safety interlocks and relay logic for motor protection. All components are arranged within a standardized industrial enclosure with front-access panel. The drawing utilizes metric measurements throughout and includes provisions for connecting to a 10HP three-phase motor, making it suitable for pump, compressor, or similar applications requiring direct motor starting.
