Westfalia fridge cutout relay replacement

[aisha]

The fridge cut-off/leisure battery charging relay under the drivers seat in my westy has died.
I was told (here) before that I need the 5 pin B-type configuration to replace this relay with (two 87 pins that are isolated from each other until relay is activated) - so fridge remains off, and main and leisure batteries disconnected from each other until the engine is running.
However, this diagram would seem to suggest otherwise:

What have other people replaced theirs with?
Thanks

After studying the above diagram for a while, I've decided that I don't need the B-type with 87 pin isolation, as the charger doesn't need to be isolated from the driving battery (sounds logical, but maybe I've read the diagram wrongly).

Gonna go ahead and buy the twin make and break here:

The original is rated to 30A so it should be a good match...

It should still keep the leisure battery isolated from the driving battery when not running, and fridge only connected when the engine is running.

To be honest, yes that relay will work, however, given the chance to upgrade (that one is just 30amp) I would go for the dedicated Lucas or Durite split change relay.....you might need to change a couple of terminal ends but they are much more robust at 60 & 70amps respectfully:
