I have only seen the Keysight shunt and shunts from Omicron in the style you have indicated. Omicron stop at 32A, but they are an horrific price for what they are.
As the others have done, I just buy a current shunt to suit and house it in a small case, or if I am feeling really good at the time, I cut the box down to a smaller size and can achieve something similar to the Keysight shunt.
Kind regards
