Answer to this question: C: Low voltage protection
When the supply voltage suddenly drops or disappears, in order to ensure the automatic start-up of motors that drive important loads, ( ) should be installed on less important loads, ordinary electrical loads, or circuits to trigger a trip. C: Low voltage protection
When the supply voltage suddenly drops or disappears, in order to ensure the automatic restart of motors that drive important loads, (c) should be installed on less important loads, ordinary electrical loads, or circuits to trigger a trip. A: Overcurrent protection B: Instant current cutoff protection C: Low voltage protection D: Low voltage and overcurrent protection
The correct answer is C. Low voltage protection
I think I’d just guess and choose option D
