1sna115322r1500 – m4/6.d2.2 double deck term

Why Choose the TE Connectivity 1SNA115322R1500 M4/6.D2.2 Double-Deck Terminal Block?

The TE Connectivity 1SNA115322R1500, designated M4/6.D2.2, is a grey double-deck screw-clamp feed-through terminal block from the ENTRELEC SNA range. Its two-level construction provides two independent circuits within a compact 6 mm footprint, making it particularly useful for high-density industrial control and signal wiring.

The M4/6.D2.2 has a rated cross-section of 4 mm², an IEC rated current of 32 A and an IEC rated voltage of 630 V. Each level provides two screw-clamp connection positions, with conductor capacities from 0.2–4 mm² for rigid conductors and 0.22–4 mm² for flexible conductors.

Measuring 65.5 × 6 × 52 mm (H × W × D), the terminal combines high wiring density with dependable screw termination. Its grey polyamide 6.6 housing, UL 94 V-0 flammability rating and operating temperature range from -55 to +110 °C support reliable use in industrial panels, automation systems and machinery.

Key Advantages

• Double-deck construction provides two independent circuits within one compact terminal footprint.
• 4 mm² rated cross-section for common industrial signal and control conductors.

Reliable Double-Deck Connections for High-Density Wiring

Double-deck terminal blocks increase connection density by placing two electrically independent feed-through circuits within a single terminal footprint. The M4/6.D2.2 therefore enables more connections to be installed along a given length of DIN rail while retaining clear, individually accessible screw-clamp termination points.

With an IEC rating of 32 A at 630 V, an 8 kV impulse withstand rating and conductor capacity up to 4 mm², the M4/6.D2.2 provides dependable performance for industrial signal and control circuits. Its compatibility with both G32 and TH35 DIN rails also supports straightforward integration into a wide range of panel designs.

Typical Applications

• High-density industrial control panels.
• PLC and automation system wiring.
• Industrial signal circuits.
• Machine control cabinets.
• Process control and instrumentation panels.
• Switchgear and electrical distribution assemblies.
