DELTA i-system

DELTA i-system is Siemens' premium square-format wiring accessory platform built on interchangeable 55×55 mm frames. Schuko Type F sockets dominate the range at 16 A / 250 V, available in Titanium White, Carbon Metallic, Aluminum Metallic, Soft Black, and Electric White finishes. Safety options include increased touch protection, overvoltage protection with LED status, hinged covers, and labeling fields. The range also covers a NEMA 5-15R outlet for North American equipment, a 75-ohm BNC socket for AV installations, an equipotential bonding box, and blank cover frames. A 100-pack Profibox contractor kit in Electric White supports volume installation. The modular frame system allows color and finish changes without rewiring — the cover plate and rocker insert snap into the same flush-mounted sub-frame.
