Typically the letter directly preceding the rated voltage indicates the “Breaking Capacity” of the fuse. This is normally represented by the the letter “L” for low or “H” for high. That’s all I’ve got.

This is a standard 5 X 20 mm glass tube fuse correct? None of my references show an E in a part number. Nor can I find any reference table of specifications associated with the letter E.
So guess time, These are available with wire leads, some have called them E-leads. Maybe some manufacturer used that in its part number. Has some one cut the wire leads off to use it in a standard fuse holder?

I came across this document.
https://www.littelfuse.com/tec...ap-marking_guide.pdf

Breaking Capacity:
L = Low (glass)
H = High (ceramic)
E = Enhanced (glass)

Looking further, I came across this.

For IEC fuse types, a symbol denoting the rated breaking capacity is indicated directly on the
component: L standing for 35 A or 10 x IN maximum, E for 150 A and H for 1 500 A

Hope this helps.

I suspected "enhanced" as well.

mark123, I think the non-"E" version will be fine.

After Patrick-SP2022 found out what the E means.
The fuse you referenced only had a breaking capacity of 35 A. The one you are replacing has a breaking capacity of 150 A, same as a Littlefuse 0219.500 MXAP available from Newark, Digi-key, or Arrow. May be Amazon, did not check.
