🔍 Key Concepts

• Difference between a single contactor and a magnetic reversing / two‑speed starter • How two contactors can be mechanically or electrically interlocked to change motor direction or speed • Role and appearance of a separate overload relay block compared with a full starter assembly

💭 Think About

• Look at which picture shows enough components to both switch power and also reverse direction or change speed of a motor, not just start and protect it • Ask yourself: if I needed to reverse rotation or select a second speed, which device has more than one power contactor that could feed the same motor in different configurations? • Which option looks like a complete starter assembly (contactor(s) plus overloads and interconnections) rather than just a single relay or overload unit?

✅ Before You Answer

• Identify which illustration shows two distinct contactor sections that could be interlocked for reversing or two-speed operation • Check for factory wiring between the two contactors, suggesting they work together as a coordinated starter, not as independent units • Make sure you do NOT choose a picture that is only an overload relay (thermal protection) or only one contactor without its reversing/two-speed partner
