Appleton VWG-1 Wire Guard for V-51 Series Luminaires, 60-150W, Steel

Under NEC it is rated Class I, Division 2, Groups A, B, C, D. Under CEC it covers Class I, Division 2, Groups A, B, C, D; Class II, Divisions 1 and 2, Groups E, F, G; Class III; and Enclosure 3R. That makes it a fit for combustible dust and fiber areas as well as Division 2 vapor areas, but it is not a Class I Division 1 fixture, so it should not go in an opening classified Division 1 for flammable gases or vapors.

It takes a medium base incandescent lamp from 60 to 300 watts. The socket is porcelain with a brass screw shell and is shock absorbing, which is what keeps filament life reasonable on vibrating structures like conveyor framing or tunnel walls.

No. The V-51 is rated for a maximum input voltage of 150V, so it suits 120V circuits but not 277V lighting branch circuits. If your building runs 277V lighting, this fixture is the wrong choice for that circuit.

It is an enclosed, gasketed fixture built for wet, dirty and corrosive areas. The mounting hood and globe adapter are malleable iron with a triple coat finish of zinc electroplate, chromate and epoxy powder coat, and a neoprene rubber ring seats in the neck of the reflector to seal and cushion the glass globe. The CEC listing includes Enclosure 3R, which is a rain-tight rating.

The V-51 platform is not one fixture with simple options. It is a set of distinct sub-series (VGL, VPG1, VA, VGAT, VXHA, VWG, VC, VD and others), each a specific combination of mounting hood, globe material and guard style for 60-300W hazardous location lighting. Catalog number VWG-1 is one of those combinations. If the hood, globe or guard you need is different, the correct move is to order the matching sub-series catalog number, not to substitute parts on this one.

The V-51 platform is offered in pendant, 45 degree stanchion, and a range of ceiling and wall mountings. The mounting style is built into the sub-series you order rather than being a field-adjustable option, so pick the sub-series that matches how the fixture lands on your structure.

It comes with a connection block, so the electrician lands supply conductors on the block rather than splicing to fixture leads inside the hood. Combined with the unitized construction, that is what keeps install labor down on a large run of these.

No clamps. The steel guard snaps into two recesses in the globe adapter, so it goes on and comes off without tools. The guard is finished in zinc electroplate and porcelain enamel.

Those are exactly its stated applications: storage and warehousing, tunnels and subways, chemical plants and processing facilities, plus general hazardous, industrial, wet, corrosive or dirt-prone areas. The malleable iron body and cushioned porcelain socket are aimed at spots where a standard sealed luminaire gets hit or shaken.
