Can anyone identify this component, possibly a varistor?
I would say it is a capacitor 1n5 F. The 400 V AC and peak 4kV rating, along with all the other certification logos suggest that it is rated for safe use on mains.
It's a 1.5 nF Mica cap for mains use.
This is fun
It's a 1.5nF 400V AC, 4kV AC test, Ceramic. Note that while it's certified for flamability, it's not suitable for use (unprotected by a fuse) across the mains as it doesn't have an X or Y marking.
Edit: Y2 would require 5kV test and Y1, 8kV.
Thanks everyone.
I saw the 1n5 marking,
but it never occured to me that it could be anything but a varistor.

The markings say it has mains use approval for Switzerland, Sweden, Germany, US, GB, which then automatically leads to approvals for other countries, generally all of the EU. It's approved for Y and X1 use.
It's ceramic and older than 1994, where the approval markings changed (X or Y specifically marked on the part).
BS 415 "Specification for safety requirements for mains-operated electronic and related apparatus for household and similar general use " withdrawn Nov. 1995
Good find on the datasheet. I must admit to being a bit puzzled to see a BS415 marking on what looked to be a relatively modern (well at least, clean) looking part.
Sadly topical.
