Why Choose the TE Connectivity D4/6.NTLP Installation Terminal Block?
The TE Connectivity D4/6.NTLP, manufacturer part number 1SNA110439R2200, is a compact 4 mm² three-level screw-clamp installation terminal block from the ENTRELEC SNA range. It combines neutral disconnect, live feed-through and protective earth connections within one DIN rail-mounted terminal, providing an efficient solution for distribution cabinets and industrial installation wiring.
The D4/6.NTLP uses a grey, blue and green/yellow configuration to distinguish its connection functions clearly. With a narrow 6 mm spacing, three connection levels and a nominal conductor capacity of 4 mm², it enables several circuit functions to be accommodated in a compact footprint while retaining straightforward access for installation and maintenance.
The main circuit is rated at 30 A and 320 V, with a rated impulse withstand voltage of 4000 V and a short-time withstand current of 480 A for 1 s. The terminal accepts rigid and flexible conductors from 0.2–4 mm², provides IP20 protection at the main terminals and mounts on G32, TH35-7.5 or TH35-15 DIN rails. Part number 1SNA110439R2200 is supplied in a pack quantity of 20 pieces.
Key Advantages

Compact Neutral, Live and Earth Distribution
The D4/6.NTLP combines three important installation wiring functions within a single 6 mm wide terminal block. Its neutral disconnect level provides a practical means of isolating the neutral circuit for testing or servicing, while the live feed-through level provides continuous conductor connection and the protective earth level supports the associated grounding connection.
This three-level arrangement reduces the amount of DIN rail space required compared with separate terminals for each circuit function. Combined with screw-clamp termination and compatibility with several common DIN rail profiles, the D4/6.NTLP provides a practical solution for structured distribution cabinet, control panel and installation wiring.
Typical Applications
- Electrical distribution cabinets.
- Neutral, live and protective earth distribution.
- Industrial control panels.
- Building installation wiring.
- Automation and machinery electrical cabinets.
- Compact three-level DIN rail terminal assemblies.
- Commercial and industrial electrical installations.
