Why Choose the TE Connectivity 1SNA115271R2200 M4/6.D2 Grey Double-Deck Terminal Block?
The TE Connectivity 1SNA115271R2200, type M4/6.D2, is a grey 4 mm² double-deck screw-clamp feed-through terminal block from the Entrelec SNA range. Its two-level construction provides two independent feed-through circuits within a compact 6 mm terminal width, making it particularly suitable for high-density industrial control and automation wiring.
The M4/6.D2 provides four poles across two independent circuits, with two conductor positions and two levels incorporated into one DIN rail-mounted terminal. Proven screw-terminal technology provides secure conductor termination, while the double-deck configuration helps panel builders increase wiring density without requiring additional DIN rail length.
Rated at 32 A and 800 V IEC, the 1SNA115271R2200 accommodates conductors up to 4 mm² / 12 AWG. It also provides a 480 A short-time withstand current for 1 s, an 8 kV impulse withstand rating, IP20 protection and a wide -55 to +110 °C operating temperature range.
Key Advantages
- Double-deck design provides two independent circuits in only 6 mm of DIN rail width.
- 32 A, 800 V IEC rating for industrial signal and control circuits.
- Accepts conductors up to 4 mm² / 12 AWG.

- 6 mm product spacing.
- 32 A IEC current rating.
- 800 V IEC voltage rating.
- 480 A / 1 s short-time withstand current.
- 8 kV IEC impulse withstand voltage.
- Grey PA66 insulating housing.
- IP20 and UL 94 V-0 construction.
High-Density Double-Deck Terminal Connections
Double-deck terminal blocks allow two independent electrical circuits to occupy the DIN rail width normally required by a single conventional terminal. The M4/6.D2 achieves this by arranging two feed-through circuits vertically within its 6 mm-wide housing, providing four poles across two levels while maintaining electrical separation between the circuits.
This configuration is particularly valuable in densely populated control cabinets where available DIN rail space is limited. With its 4 mm² conductor capacity, 32 A IEC current rating and secure screw-clamp terminations, the TE Connectivity 1SNA115271R2200 provides a compact solution for organised signal, control and industrial wiring while retaining straightforward conductor access and circuit identification.
Typical Applications
- High-density industrial control panels.
- Factory automation and process control systems.
- Machine control cabinets.
- Signal and control wiring.
- PLC and I/O marshalling assemblies.
- DIN rail junction and distribution systems.
- OEM machinery and industrial panel building.
