Why Choose the TE Connectivity 1SNA115166R1100 M4/6.D1 Shunted Terminal Block?
The TE Connectivity 1SNA115166R1100 is an M4/6.D1 double-deck shunted feed-through terminal block designed to provide compact and reliable signal connections within industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA terminal block series, it uses proven screw clamp technology and a vertically interconnected two-level design to maximise wiring density on the DIN rail.
The M4/6.D1 provides one feed-through circuit with vertical interconnection across its two levels. It has a rated conductor cross-section of 4 mm², an IEC current rating of 32 A and an IEC voltage rating of 800 V, making it suitable for dependable signal and control wiring in professional electrical installations.
With a narrow 6 mm spacing and dimensions of approximately 65.5 × 6 × 52 mm, the 1SNA115166R1100 provides two-level connectivity while conserving valuable DIN rail space. Its grey Polyamide 6.6 housing, IP20 protection rating and compatibility with G32 and TH35 DIN rails make it a versatile solution for industrial panel building.

Space-Saving Connections for Industrial Control Systems
Double-deck terminal blocks increase wiring density by placing connection levels vertically rather than requiring separate terminals alongside one another. The M4/6.D1 takes this approach further by electrically interconnecting its two levels, creating a single shunted feed-through circuit that can simplify common-potential and signal distribution within densely populated control panels.
The ENTRELEC SNA screw clamp system provides secure conductor retention and straightforward installation using conventional tools. Combined with compatibility for commonly used G32 and TH35 DIN rails, the M4/6.D1 is well suited to new control panel construction, machinery wiring and maintenance of existing industrial terminal assemblies.
Typical Applications
- Industrial electrical control panels.
- Factory automation and machinery wiring.
- Signal and control circuit distribution.
- Common-potential and shunted wiring applications.
- Instrumentation and process control systems.
- Space-constrained DIN rail terminal assemblies.
