About this detail

An electrical schematic details a 480-volt three-phase motor control circuit originating from a motor circuit protector and branching into a solid-state overload relay and motor contactor. A control power transformer steps down the voltage from 480 to 120 volts to supply the control logic including a local control station with start and stop pushbuttons. Additional relay logic incorporates auxiliary contacts, a motor starter coil, and digital inputs connected to a control module with ethernet switch capability. Safety and status monitoring features include fault indication, high motor temperature switching, and door-mounted display lights.
