Blade fuse marked E

[BillandHelen]

Hi, my inet x has a blade fuse marked with an E in the 12v fuse board in our van. We are away for the weekend in Melrose and it’s been sub zero since we arrived. Van was v cold, got the diesel heater on which then allowed the pump to work and got water ok. However my inet x fuse, not on the panel but in the 12v fuse board, blew 3 times, it’s a resettable fuse so got it going again ok with a spare.

Questions, what does E mean on a fuse? I understand my inet panel is 3amp? It’s all been working fine now for a few hours but I’ve got a bit of a worry about why it blew, could it just have been the cold and damp?

Also are Halfords ok to buy blade fuses from re quality?

Thank you for any advice.
