The 5UB1520 combines two independent safety standards in one DELTA i-system SCHUKO socket: green SV circuit identification per VDE 0100-710 and increased touch protection per VDE 0620. The green housing tells electricians this outlet is fed from the highest-priority safety supply; the recessed contacts and narrowed pin apertures prevent children from accessing live metal. For pediatric wards, special-needs school facilities, and child-accessible hospital areas on safety circuits, no other i-system green socket meets both requirements.

Why would a safety circuit socket need increased touch protection?

At first glance, the two concerns seem unrelated: SV color coding is about circuit integrity during a mains failure, while increased touch protection is about preventing accidental contact. But in practice, safety circuits often run through spaces occupied by vulnerable populations — pediatric wards, nurseries in special-needs facilities, hospital waiting areas. In these environments, both requirements apply simultaneously: the socket must stay powered during an outage (SV requirement) AND must resist children's probing (VDE 0620 requirement). The standard green 5UB1512 satisfies only the first; the 5UB1520 satisfies both.

How does the 5UB1520 differ from the 5UB1512?

The electrical core is identical — both are 10/16 A, 250 V, 2P+E Type F SCHUKO sockets with screwless plug-in terminals and 55 × 55 mm DELTA i-system plates in green. The only difference is contact protection: the 5UB1520 has VDE 0620 increased touch protection (recessed contacts, narrowed apertures); the 5UB1512 has standard protection. All other parameters — including the green SV color, IP20 rating, thermoplastic halogen-free material, and Spain origin — are the same. The PN suffix pattern is consistent with the rest of the i-system range: -1xx series = standard protection; -2xx series = increased touch protection (5UB1512 vs 5UB1520 for green; 5UB1513 vs 5UB1521 for orange; 5UB1514 vs 5UB1522 for red).

Frequently Asked Questions

Are there orange and red equivalents with increased touch protection?

Yes — 5UB1521 (orange ZSV) and 5UB1522 (red emergency/standby) complete the 5UB152x sub-family, each offering the same VDE 0620 increased touch protection with their respective VDE safety color coding. All three share identical electrical ratings, terminal type, and plate dimensions.

Does the increased touch protection affect the SV circuit's electrical performance?

No — the increased touch protection is a purely mechanical feature of the socket front face. It does not add impedance, does not affect the 16 A current rating, and does not interact with the upstream SV power supply or transfer switch. The safety circuit sees this socket as electrically identical to the standard 5UB1512.
