132. Which of the following illustrated manual motor starters represents the wiring diagram illustrated in figure «A»
Choice 1 is correct; it is the only device that matches the schematic in figure A, which depicts a three-pole magnetic motor starter with integral overloads and separate start/stop pushbuttons controlling a coil. The schematic shows three main power contacts and overload elements feeding a three-phase motor, operated by a control circuit for remote start/stop functionality, a feature present in device 1.
