🔍 Key Concepts

• electromagnetic coupling function and how torque is transmitted • the difference between a protective device (like an overload trip) and a mechanical/torque limit built into the coupling • how torque is intentionally limited to prevent damage to the driven machinery

💭 Think About

• Ask yourself: which choice refers to a built‑in torque limit related to the coupling’s magnetic or mechanical characteristics, rather than an external protective device? • Which item would be specified by the coupling manufacturer as a maximum torque rating, beyond which the coupling will start to slip or disengage? • Which options clearly do NOT belong to electromagnetic couplings (for example, parts more associated with boilers or shaft protection devices)?

✅ Before You Answer

• Eliminate any option that is clearly associated with boiler construction rather than rotating machinery couplings. • Distinguish between an electrical protective trip in a control circuit and a torque-limiting feature in the coupling itself. • Focus on the choice that best describes the maximum torque capacity rating of the coupling before it loses synchronization or grip.
