Motor Change-out Plugs and Arc Flash

I was recently at a conference where a vendor was showing their disconnect/plug combination that they claim removes the need for PPE due to their safety shutters and dead front construction. I don't see anything that talks about the devices interrupt rating with out talking about the upstream protection device. I was under the impression that if the incident energy is calculated there is a PPE requirement. Is it legitimate to say this removes the need for PPE? 

Thoughts?

 

Thanks,

 

Jeff
