Plastic insulating material Vo

[intense]

Can anyone shed some light on the above material specification . I need to know if what V o actually is ? ie a material type or some to do with flame retardent class for insulating materials?

The above is used in a description for a comb bus bar assembly for single phase mcb distribution.

V-0 (that's "VEE ZERO&quot is an Underwriters Laboratories classification for flame resistance of materials. I have only heard it in regard to plastics. Most plastics manufacturers have formulations of their basic resins that meet this and other UL classifications. See:

The standard to reference is UL 94. This deals with the flammability of materials. V0 is a mediocre rating.

And as tcampbel stated, check it out at

For bus bar application, V-0, which is flame retardancy at the best as per under writers laboratory specification, is necessary. Polycarbonate sheet, with V-0 specification is the right material to make shroud for bus bars, we are already doing for some local switchgear companies.
