A thermostat embedded in the winding of a motor provides?

• A. Low starting inrush current
• B. Inherent protection
• C. High inductance
• D. Replica protection

Answer: (B)

Thermal protection is the key idea: an embedded thermostat monitors the winding’s temperature and automatically interrupts current when it overheats. This built-in safeguard protects insulation and prevents damage or fire, giving the motor inherent protection without needing external devices. It doesn’t reduce starting inrush—that’s controlled by starting methods or soft-start techniques—and it doesn’t change the inductance of the winding. The notion of replica protection isn’t applicable here; the thermostat provides real, automatic protection tied to temperature.
