seems logical that its the same as the other two. Z.A.2413.

Hmmm... the two I have also say CAT. No. Z.A.2413 on them, but it's possible that's only the cover because the base of the unit has CUT OUT AUTO No. 6
on the edge of the base next to the cable entry, and CAT No. Z.B.2478 on the opposite end.
I don't think they're an overcurrent relay, more likely the reverse, where they will disconnect the battery from the supply once the charging current falls to a low enough level.
The two tubes lining up with the holes in the cover appear to be for an operator's lamp.
I managed to get the back off one unit, and there's a flat coil (possibly a heating element to protect against frost) inside.
Anyway, they weigh around 590g (or 1lb 4.5 oz for this Imperialist), and I can probably mail you one (or both) if they're suitable and you can't get one locally.
