OSHA-Yellow Fiberglass Enclosures
Product Announcement from Signature Enclosures
These fiberglass enclosures were originally produced for a major railway. Each enclosure was manufactured with non-tapered sides, then bolted together for straight line installation.
These are used to house high-voltage DC switches. The construction is NEMA 4X, with an OSHA-yellow gelcoat. All of the external metal parts (hinge, handle, fasteners) are insulated against electrical arcing.
