Power Distribution Block in NEMA4 box in a Class 1 Div 2 Location

[lpena]

Is it OK to use a power distribution block to distribute 480VAC to some motors in a class 1 DIv 2 location? I would like to use the following PDB:

I plan to install this PDB in a NEMA4 box. Is this allowed by NEC? I tried to look for PDBs for hazarodus locations but i could not find any.

Thanks

Your link has a problem.

If otherwise used within their intended design applcation, there is no additional prohibition with created by use in Class I, Division 2.

Here is some information about the PDB. It is a UL recognized device. As i mentioned before, i plan to install it inside a NEMA4 enclosure in a class 1 Div 2. I just want to make sure it is OK to do so. Thanks

Here's your problem. That is a UL "Recognized Component" (the backwards "UR"). That means it is intended to be used in specific equipment and has no "general" application. Class I, Division 2 has no bearing, but it is possibly a misapplication as you have described it.
