You were given the shoes between an MCB and a fuse, which one will you choose? Well as for wild gifs, you prefer an MCB over a fuse, well because of technical issues. But is your choice correct? I think not. From their trip characteristics, a fuse is way better for overcurrent problems of higher current trading. While an MCB is way better for lower overcurrent problems. You can see for the same overcurrent of 10 times the nominal current, the trip time of MCB is way higher than that of a fuse. The choice of a fuse or MCB is also application specific. For robust applications such as this motor, you might just want to go with the circuit breaker or an overcurrent relive into as well. For sensitive applications such as these power electronic devices, you would want to use a fuse as well. That is all for today. Leave a like, comment, share and subscribe. And have a nice day!
