Xps2 blown fuse

[Antonio1]

Back from holiday after plugging and powering on everything circuit breaker went off.
Xps not lightening.
Fuse looks blown.
No replacement one at its side
Value: 1.35 A 250 V. Do not even know wheter the correct value as bought the unit used.
Please advice

No, that appears to be the incorrect rating - it will say the correct fuse rating on the rear of the unit near the fuse holder itself.

I would purchase a few of them from a Naim dealer as they will stock the correct ones. FWIW - i purchase mine online from dealers such as Tom Tom Audio.

See here for more information - Equipment Fuses

Hi thanks, so why was there an incorrect value fuse?
I’ve found the exact replacement inside an hicap dr ( there were two of them) and seems to work ok now

[Stephen_Tate]

The HiCap one is an incorrect rating for a XPS2 and for safety reasons should not be used as it’s of a higher value

Equipment Fuses

Should the protection fuse blow on any piece of Naim equipment, make sure you get the exact same make and type - this is important. Your Naim dealer can help, or else get in touch with Naim support. NEVER be tempted to bypass or “uprate” the equipment fuse. Doing so is extremely dangerous. Among other things, the fuse is there to protect against fire in the event of a catastrophic failure. Not only will you void any warranty but you will also put your home, your life and those of your fam…

Ok I’ll definitely get a Couple fro a naim authorized agent.
Thanks

Which fuse for XPS DR

That doesn’t look like an original, cetainly the ones I have seen have been clear. The correct replacement is available from RS Components. Littelfuse 2.5A T Glass Cartridge Fuse - Stock number 541-2969 Don’t worry too much that the fuse has blown. The XPS is known for blowing fuses. The correct fuse is a time lag slow blow fuse which helps stop it blowing when the unit is switched on, although that’s not always successful!

I had this happen once. After changing the fuse it didn’t re-occur for the next year or so of ownership before I replaced it with a CD555PS. It’s an occupational hazard with the XPS2 inrush current. Don’t worry about it. You are good.

I have never actually ‘bought’ any fuses for my Naim units. My dealers have always been most helpful & generous.

Same here.

Be absolutely sure to replace with exactly the correct value of fuse(s).

The one inside the XPS2, as specified by Naim is: 20mm 2.5A 250V Slow Blow / Antisurge fuses – Naim use fuses made by “Littelfuse” from their 213 series."

Available from your Naim dealer or from RS Components.
I bought a decent number from RS Components as the XPS2 does have a tendency to blow fuses rather too often. That’s why I bought a box of them !

@Blythe

Naim use fuses made by “Littlefuse”

Littelfuse. You have to spell it right if you are searching for it…

[Blythe]

Autocorrect “corrected” it. I’ll try and amend my post!

[damy79]

I found someone suggest Littelfuse 213 series and other 218. Which is the correct one?

[Richard.Dane]

For an XPS2 you want the Littelfuse 5 x 20 2.5A T Glass Cartridge Fuse, Part No. 021302.5MXP

[thenaimsdave]

Same with my dealer. Maybe it is the same one ?

[IanRobertM]

@thenaimsdave

Maybe it is the same one ?

Choice of two - past & present, both LE postcodes…

[thenaimsdave]

CH code actually

[IanRobertM]

@thenaimsdave

CH code

Definitely not, then.

CH = Chester…?

LE = Leicester, definitely.

[thenaimsdave]

Yes CH is Chester
