The 5UB1512 is the green SV-designated SCHUKO socket in the DELTA i-system family. Green is the highest-priority color in the VDE safety hierarchy — Sicherheitsversorgung (SV) circuits that must maintain power under all conditions, including during a general mains failure. This is the entry-level identification variant: the green housing alone provides the circuit designation, with standard contact protection and no additional features.

What makes SV different from ZSV and emergency circuits?

VDE 0100-710 defines three safety circuit tiers, each with a dedicated socket color. SV (green) is the top tier — equipment whose failure directly endangers human life: fire alarm control panels, smoke and heat extraction fans, emergency lighting in escape routes, firefighter lifts. ZSV (orange) is the middle tier — additional safety supply for equipment that must remain operational for safety but where brief interruptions are tolerable. Emergency/standby (red) is the lowest safety tier — normally de-energized outlets that only activate when backup power kicks in. Connecting a ZSV load to an SV outlet wastes SV capacity; connecting an SV load to a ZSV outlet is a code violation.

What should I verify before installing green SV sockets?

Three checks before commissioning: (1) confirm the circuit behind this socket is actually fed from the SV distribution board — the green color must match the electrical reality, not just the installer's preference; (2) verify the upstream SV source (battery, generator, or separate utility feed) has enough capacity for the planned load; (3) document which SV circuit number this outlet belongs to — unlike the 5UB1515 with its integrated labeling field, the 5UB1512 has no built-in labeling, so circuit identification must be handled externally.

Frequently Asked Questions

Does the 5UB1512 have increased touch protection?

No — standard contact protection only. If you require green SV identification with increased touch protection (erhöhter Berührungsschutz per VDE 0620), use 5UB1520, which adds recessed contacts and smaller pin apertures while keeping the same green SV color coding and 55 × 55 mm plate format.

Can green SV sockets share a multi-gang frame with standard white sockets?

Yes — the 55 × 55 mm DELTA i-system format is uniform across all colors. A common panel layout places one or two green SV sockets next to white general-purpose sockets in a single frame, making safety circuits immediately distinguishable without additional labeling.
