A(n) __________ circuit breaker has a trip time that gets faster as the fault current flowing through it gets larger.
A) dual-element
B) inverse time
C) plug fuse
D) type S

Question

Quizplus · Accepted Answer

An inverse time circuit breaker has a trip time that decreases as the fault current increases, providing more protection against high-current faults. A dual-element circuit breaker has two different trip elements that provide protection against both high and low current faults. A plug fuse is a type of overcurrent protection device that has a metal wire that melts when the current becomes too high, while a type S circuit breaker is a specific type of dual-element circuit breaker that is used in specific applications. Therefore, the best choice for a circuit breaker with a trip time that gets faster as the fault current increases is an inverse time circuit breaker.
