Overload protection is designed with inverse time-delay trip characteristics.This means the ____ the overload current the faster the circuit will open, but a smaller overload would take much longer to open the circuit.
A)average
B)smaller
C)shorter
D)greater

Question

Quizplus · Accepted Answer

Inverse time-delay trip characteristics means that as the overload current increases, the time taken for the circuit to open decreases exponentially. Therefore, greater overload current will cause the circuit to open faster than smaller overloads.
