The 5UB4650 is a gray single Schuko socket outlet from the Siemens DELTA series, distinguished by its die-cast metal hinged cover. Rated for 16A at 250V, it is flush-mounted in a standard 60mm wall box with claw and screw fixing. The die-cast cover is the defining feature — it provides mechanical protection for the socket face that a standard open outlet or plastic-hinged cover cannot match.

What does the die-cast hinged cover protect against?

The cover provides three layers of protection when closed: (1) mechanical — the rigid metal lid shields the socket face from impact, knocks, and objects leaning against the wall; (2) dust and debris — the cover seals the socket openings when not in use, keeping out construction dust, workshop particles, and household debris; (3) accidental contact — a closed cover prevents children or objects from touching live contacts. The cover does NOT improve the IP rating beyond IP20 — this remains an indoor-only socket. For wet-area protection (IP44/IP55), Siemens offers sockets with gasketed hinged covers in other ranges.

Die-cast metal vs plastic hinged cover — why pay for metal?

Plastic hinged covers rely on spring-loaded flaps that can snap off if knocked from the side. A die-cast metal cover is rigidly hinged with a metal pin — it withstands lateral impacts that would break a plastic flap. In workshops, garages, and utility rooms where tools, ladders, and equipment move past wall sockets, the metal cover is a meaningful durability upgrade. The weight difference is substantial — the 5UB4650 weighs 0.468kg, roughly five times a standard single Schuko socket, almost entirely due to the metal cover and hinge assembly.

Is the 5UB4650 still in production?

Some distributors (Farnell/Element14) list the 5UB4650 as no longer stocked, while others (RS Components) continue to offer it. This pattern suggests the product may be in run-out phase — available through existing channel inventory but not actively replenished at all distributors. For new projects, check current availability with your preferred Siemens distributor. If the 5UB4650 is unavailable, the DELTA miro and DELTA i-system ranges include single sockets with hinged covers in various finishes that may serve as alternatives — though none with a die-cast metal cover in the same gray finish.

Frequently Asked Questions

Does the metal cover need to be earthed?

No. The die-cast cover is mechanically connected to the socket body but is electrically isolated from live parts by the thermoplastic housing. Schuko sockets earth via the side spring clips (CEE 7/3), which engage the plug's earth contacts — the cover itself does not carry current and does not require a separate earth bond.

Can I replace just the cover if it gets damaged?

Siemens does not offer the die-cast cover as a separate spare part. If the cover or hinge is damaged, the complete socket must be replaced. For high-wear locations where cover damage is likely, consider stocking a spare 5UB4650 or evaluating whether a standard open socket with an external protective enclosure offers better maintainability.
