Can I get benefit's from use MCB with Fuse ?
if I used MCB with fuse, I can have circuit cutted faster when shorted (with Fuse), and cutted faster when overload (with MCB), and I can replace Fuse more safely, because I wire MCB before Fuse, also MCB have greater breaking capacity, 6kA (MCB) vs 150kA (Fuse), so.. in case MCB is faulted and can't cut circuit, fuse is cutted the circuit
Disadvantages : More expensive, need enough space in panel, also need lots of wiring, with MCB or Fuse only, I just use comb busbar, with this system I use comb busbar and wire
Is that a good idea ?
What do you think ?
and Is really Fuse can cut circuit faster than MCB in case of short circuit ?
