Why Choose the TE Connectivity D4/6.P.T1 1SNA199220R0000 Triple-Deck Earth Terminal Block?
The TE Connectivity D4/6.P.T1 1SNA199220R0000 is a compact multi-level earth terminal block from the Entrelec SNA range, designed for protective grounding in high-density industrial control and signal wiring. Its multi-level construction provides seven earth connections, making it particularly useful where multiple protective conductors need to be organised within limited DIN rail space.
The D4/6.P.T1 uses proven screw-clamp termination technology and accommodates conductors up to 4 mm² / 12 AWG. With six wiring positions, a 6 mm terminal width and DIN rail mounting, it provides a space-efficient solution for protective earth distribution in machinery, automation panels and other industrial electrical assemblies.
Designed as a dedicated ground terminal, the 1SNA199220R0000 provides a short-time withstand current rating of 480 A for 1 s. Its screw connections use a specified tightening torque of 0.5 N·m, while compatibility with G32, TH35-7.5 and TH35-15 rails enables flexible integration into new and existing terminal assemblies.

Compact Multi-Level Protective Earth Distribution
The D4/6.P.T1 is designed to consolidate multiple protective earth connections into a compact DIN rail footprint. Its multi-level architecture provides seven earth connections, helping panel builders organise grounding conductors without requiring a separate full-width terminal for every connection point.
Screw-clamp termination provides a familiar and robust connection method for industrial panel construction. Combined with the narrow 6 mm spacing and compatibility with several common DIN rail profiles, the D4/6.P.T1 is particularly suited to densely populated control cabinets where efficient use of rail space is important.
Typical Applications
- Protective earth distribution in industrial control panels.
- PLC and factory automation cabinets.
- Machine control and OEM electrical systems.
- High-density grounding and signal wiring assemblies.
- Industrial switchboards and control equipment.
- Modular DIN rail terminal installations.
