Yes, this will be a big improvement in electrical safety. Probably cost is the big reason why it isn’t done more. It’s always difficult to convince management people to spend more than they have to for any installation.
One thing we did as a temporary measure with MCC’s and switchgear was install custom-made time delay close/trip switches, to allow personnel time to simply get out of the way while the breaker closes or trips. But the need to withdraw the breaker still presents a hazard. That’s where this new withdrawal solution can make it safer.
