Typically speaking, fused are blown to protect the equipment that is fuse protected. I personally disagree that you blew a fuse because you overloaded a circuit, while I can believe you did overload a circuit. Overloading a circuit is super easy to do.
Issue 1: Exact same fuse. This means "please match the specifications" as stated in the manual and/or on the fixture itself. If you're using a fixture that uses fast-blow and you choose to go Slow-Blow, you can possibly experience the entire fixture dying as opposed to just the fuse.
Issue 2: Relating a similar but different story. I have a unit(a compressor/limiter/expander/gate) that kept blowing fuses. Odd thing, I have another one next to it in the rack(on top). Well, it just decided to start blowing fuses. Fuses DO wear, so every once in a while, a few may blow, so it's good to have a few WELL LABELLED spares laying around. After blowing 3 slow-blow fuses in a row, it was time to take that unit out of production because there has to be something wrong with it to keep blowing fuses like that. And my situation with it was the same: it would work for a few minutes and then dead.
Since you have multiple units and the same one is acting up, you got a unit that has developed a problem. Get it serviced.
In my case, the unit isn't worth servicing, I can just get a newer better unit for what I spent before.
Typically when you overload a circuit, the circuit breaker will blow. It's really a smart thing to front-end your gear with some sort of power unit that contains a circuit breaker(not a fuse). I recommend Furman units, especially any Furman units that have the circuit breaker on the front. Yeah, they cost more. Yeah, they are worth it. Better to control your mistakes. And I'm not saying you're stupid and intentionally making mistakes, but let's say you do put too many lights on a circuit and you swear you'd never use them all so theoreticaly you SHOULDN'T overload the circuit, you accidentally do and pop, house breaker dead. Better to not bug the house guys and just reset your own breaker. Even many power strips can do this. I recommend the Furmans because the also electrically and EM/RF protect your gear, which in the case of audio is really critical.
Don't start making fuse replacement decisions that aren't like-spec for like-spec. It is the way it is for a reason. Don't risk fire, lives and more for being foolish.
Call service in the morning and see what you should do next.
