Summary

• 25-pack of Phoenix Contact STTB 1,5-PV (3031526) gray double-level DIN rail terminal blocks with spring-cage connections and integrated equipotential bonding, supplied with 14 matching D-STTB 2,5 end covers and 11 gray two-position plug-in bridges.
• Each terminal block features four conductor connections across two internally connected levels, a nominal conductor cross-section of 1.5mm², and IEC nominal ratings of 500V and 17.5A. The compact 4.2mm-wide design is compatible with standard 35mm DIN rails.
• The included end covers provide insulation for exposed terminal block sides, while the two-position plug-in bridges allow electrical connections between compatible adjacent terminals.
• Listing is for 25 Phoenix Contact STTB 1,5-PV terminal blocks, 14 end covers, and 11 two-position plug-in bridges only, does not include any instructions, installation screws, or original box. Please review all photos for the exact item, condition, and components included.
• The package includes 11 gray two-position plug-in bridges marked "FBS 4." These bridges resemble Phoenix Contact FBS 2-4 GY (part number 3030118) and appear to have a matching 4.2mm pitch. However, the exact manufacturer part number could not be verified, and these accessories are not being represented or guaranteed as model 3030118. The bridges were supplied with the included STTB 1,5-PV terminal blocks and appear physically compatible based on their previous installation. Buyers should verify fitment, electrical ratings, and suitability before use. All 11 bridges are included in the package.
• This item was sourced from a new, uncommissioned equipment cabinet that was dismantled prior to being placed into service.

Product Description

• The Phoenix Contact STTB 1,5-PV is a compact double-level terminal block from the CLIPLINE Complete ST series, designed for industrial automation, control cabinet wiring, electrical distribution, and machine building applications.
• Featuring spring-cage connection technology, the STTB 1,5-PV provides secure, vibration-resistant electrical connections without conventional screw terminals. Each terminal block offers four connection points across two levels, with an integrated equipotential bond that electrically connects both levels to a common potential.
• This internal connection makes the STTB 1,5-PV particularly useful for potential distribution in industrial control systems, allowing multiple conductors to share a common electrical connection while conserving valuable DIN rail space.
• The terminal blocks accommodate conductor cross-sections from 0.08mm² to 1.5mm², with a nominal current rating of 17.5A and nominal voltage rating of 500V under IEC specifications. Each unit measures just 4.2mm wide and mounts to standard NS 35/7.5 or NS 35/15 DIN rails.
• The package also includes 14 Phoenix Contact D-STTB 2,5 gray end covers, designed to insulate exposed sides of compatible terminal block assemblies.
• Additionally, 11 gray two-position plug-in bridges are included for bridging compatible terminal blocks. These appear consistent with Phoenix Contact FBS 2-4 GY bridges, featuring a 4.2mm pitch. The exact bridge part number has not been independently confirmed from the individual accessories. It is marked on the item as FBS 4 but could not find on manufacture website. These came with all 25 Terminal Blocks, so fitment is correct for these terminal blocks.
• This complete 50-piece component package is suitable for control cabinet construction, equipment maintenance, industrial wiring upgrades, and replacement terminal block assemblies.
