Re: [RE-wrenches] 48 VDC Control fusing

2020-02-28 Thread Jeff Clearwater 

Hi Drake,

Some in-line glass fuses and holders are not rated for 48 VDC.  The 
midnite 1 Amp breaker is an good option like Ray said but sometimes I 
prefer to use a fuse so it doesn't get accidentally shut off or so I can 
bury it behind a panel so the customer doesn't have too easy access.


So If I have easy access to a place to mount DIN Rail such as in a 
Midnite E-Panel - then I use a midnite touch-fuse holder 
 
and a 1 amp fuse.  Or you can get them at any supply house like this. 



And of course it's easy enough to add a piece of DIN Rail to the back of 
any panel.


I like using this approach for fusing 24 V power supplies running the 
monitoring equipment too - again so they don't get easily shut off.


Hope that helps.

Best,

Jeff

Hello Wrenches,

It seems that inline fuse holders and glass fuses are becoming hard to 
find. What is a good way to protect 48 V DC control and 
instrumentation wires?


Thank you,

Hi Drake,

Perhaps this fuse holder will work if you want to stay with glass envelope:

We mostly use panel mount breakers for small loads:

We still use inline fuses ordered online, but Midnite Solar carries a 
whole line of DC rated breakers that go down to 1 amp.
