32a three phase isolator neutral bar?

Ah, that explains quite a bit, and means I must also apologise if I went a bit hard at you. I was treating your question like a tradesman was asking "What's a screwdriver for?" rather than a learner looking to learn.

No probs mate. This is year i get to ask stupid questions ?

As it's for a trainee I'll just add that if it's a Neutral contact will be early make / late break compared to the L1, L2, L3 contacts.
But I'll leave them to find out the importance of that.

Hard to see from the picture but is the fourth switch terminal marked as N.

Even magnified it doesn't appear to have a marking on the 4th contact, jut the arrow in the plastic case.
From the style (plastic screws) it looks to be a Europa, which also appears very similar to older Klockner style disconnectors.
There's space on the left side for another contact so it may be that the 4th contact is auxiliary and could have a 5th.
The 4th contact will have details on the side.

No it's just bare. The guys i am working with said it was the N though. Incidentally we were hooking up machines with no neutral anyway.

It's an 'Eris Industrial' 32a/20a from Yesss.

32A 4 Pole Surface Mount Isolator IP65 - https://www.yesss.co.uk/32a-4pole-surface-mount-isolator-ip65 It's one of those. We're basically using them as an emergency stop.

Strictly speaking the neutral is the separate terminal on the enclosure. The fourth switch terminal I would consider an auxiliary as it is not marked for a specific purpose and can be used for several things.

Is there any advantage/disadvantage to the way we've done it? The machinery we're hooking up doesn't use neutral so it's not used anyway.

From the link above it's shows switched neutral
