Which statement is true about nonreclose operation?

• A. The recloser will always trip faster
• B. The recloser does not operate faster than normal
• C. It guarantees accident prevention
• D. It has no effect on trip timing

Answer: (B)

Nonreclose means the recloser will trip on a fault but will not automatically attempt to reclose afterward. The key point is that the first-trip timing is still governed by the protection settings, so there’s no built-in acceleration of the trip just because reclosing is disabled. In other words, the recloser does not operate faster than normal; it simply stops after one trip and does not attempt a reclose.

This option isn’t claiming that faults are prevented in every case (that would be false), and it isn’t about having no effect on what happens after a trip—the sequence changes because there’s no automatic reclose. So the statement that best matches nonreclose behavior is that it does not speed up the trip relative to normal operation.
