About this detail

This electrical schematic details a 480-volt, three-phase motor control circuit supplied through a master control protector. A control power transformer steps down 480 volts to 120 volts alternating current to power the control ladder logic. The system incorporates a motor contactor, auxiliary relays, and a solid-state overload relay connected to a door-mounted display module with power, reset, and fault indicators. Additional digital inputs and control wiring interface with a control module that communicates via ethernet to a motor control center.
