Implications of replacing a 40A with a 125A rotary isolator.

[Billybob]

An isolator had heat damage and was replaced, not by me, but the new isolator is 125A instead of 40A. They found one and threw it on.
I locked it off last night and today it is back on line, deemed okay to run until a replacement arrives.
This is on a 20yo piece of packaging equipment.
Anyone shed some light on the safety implications on this please.
First post. Apologies if in wrong place.

If its just an isolator it makes no difference at all.

Unless the original was a fused isolator, then it sounds like a good solution to the problem.

If the 40A isolator had heat damage then it was probably not rated for the current drawn by the item it isolates. Putting a 125A isolator to handle that current is probably the wisest thing to do given that someone may have done the maths on the problem and came up with the need for a 125A isolator.
