🔍 Key Concepts

• Look closely at where the reset button is actually mounted in figure A – is it on the overload relay itself or on the enclosure door? • Remember how a thermal overload relay works – it trips on heat and usually must cool before it can be reset. • Distinguish between a door-mounted external reset and an internal reset that requires opening the starter enclosure.

💭 Think About

• From the picture, decide whether you would need to open the enclosure to touch that specific reset button. • Think about whether an overload trip on a thermal device can normally be reset immediately, or if a waiting period is usually required so the element can return to normal temperature. • Compare each choice: which ones correctly combine (1) the physical access to the button shown and (2) the behavior of a thermal overload relay?

✅ Before You Answer

• Verify whether the figure shows the reset button on the relay body or on the door face. • Verify if a thermal overload that trips on overcurrent can generally be reset instantly, or only after it has cooled sufficiently. • Eliminate any options that contradict what you actually see in figure A about button location or known properties of thermal overload cooling time.
