The Siemens 5UB1558-0KE is the Profibox kit variant of the 5UB1558 electric white Schuko socket outlet. Rated at 10/16 A / 250 V AC for flush-mount indoor installation, it includes increased touch protection, screwless plug-in terminals, claw-and-screw mounting, and a 55 × 55 mm cover plate — all identical to the base 5UB1558. The -0KE suffix designates bulk packaging: 100 sockets in a single Profibox, approximately 400 × 500 × 200 mm.

When does the Profibox make sense for touch-protected sockets?

The 100-pack is aimed at contractors fitting out residential or commercial buildings where increased touch protection is mandatory — kindergartens, schools, hospitals, hotels, and multi-family housing across much of Europe. When every socket in the building must have the shutter, and the same electric white finish is specified throughout, buying 100 at a time in bulk packaging reduces per-unit cost, eliminates cardboard waste, and saves the cumulative hours of opening individual retail boxes. For smaller jobs, the single-unit 5UB1558 or the 10-pack 5UB1558-0KK are more practical.
