No, those Vs mean it's a 70 deg. rated PVC/PVC cable. *What you need is
85 deg. harmonised type H07BN4-F (UK CMA code 3183TQ), 1.5 mm^2 3-core.

I've always used 2.5mm2 butyl rubber flex, its a fair bit more
capable. Not only does the flex connect to hot terminals, but it also
heats up due to current flow, both need to be taken into account.
