Fuse to fuse coordination
WebMar 15, 2016 · If a fuse is upstream of the given fuse, there should be clearance between the bands of each fuse curve. The same is true if the upstream device is a low-voltage circuit breaker (row 1, column 3). … WebAug 7, 2024 · Response Time. Fuse reaction time is 0.002 seconds, while circuit breaker response time is between 0.02 and 0.05 seconds. Due to the speed at which the metal fuse melts, fuses have an advantage over circuit breakers in that they can interrupt the flow of power more quickly.
