## Questions & Answers

**Q: Looking for:  120 v~, 60 hz (t 4.0 ah 250 v) fuse    ...would this be the same?**
A: Yes, but there are two types. Fast acting, and time delay. Research what your need will be

**Q: Will this fit in a EV 15inc power speaker?**
A: I am not 100% sure.  I got them for my Cerwin vega speakers.

**Q: The description says these will also work on 125v. Is that true? If so, why is it listed as 250v?**
A: Fuses are labeled with a maximum operating voltage using a 250v rated fuse on a 125v system is perfectly fine. Using a 125v fuse on a 250v system isabsolutely wrong.

**Q: Is this the same as a replacement for a t4al250vp fuse? i'm just not sure what the 'p' means since it's not showing up in the item name or description**
A: I am not knowledgeable in the subject matter. I repair my tools as Do It Yourself person. Im not familiar with the electronic compatability. I just replaced the burnt fuse with the one that was the same number. Thx JB

*by H***K on 15 May 2020*

Arrived quick. Doesnt match the photo perfectly but it they work just fine. The first fuse did blow right away and the 2nd one I put in didn't, so not sure if it was an issue with the fuse or the product I was putting them in.
