Why Choose the TE Connectivity 1SNA146104R2300 D2.5/6-DA.N.EX Triple-Deck Terminal Block?

The TE Connectivity 1SNA146104R2300, manufacturer designation D2.5/6-DA.N.EX, is a blue triple-deck terminal block designed for compact, high-density conductor termination in industrial control, automation and appropriately engineered hazardous-area installations. Part of the established ENTRELEC SNA terminal block range, its three-level construction allows multiple connections to be accommodated within a narrow DIN rail footprint.

With a 2.5 mm² rated cross-section and just 6 mm spacing, the D2.5/6-DA.N.EX is particularly useful where panel space is limited and a high number of circuits must be organised efficiently. The blue polyamide housing provides clear visual identification, while the three connection levels enable compact circuit grouping without internally bridging the individual levels.

The terminal block is an Ex e explosion-protected version and belongs to a product family covered by ATEX certification for incorporation into appropriately designed hazardous-area equipment. It mounts on G32, TH35-7.5 and TH35-15 DIN rails and offers a broad -55 to +110 °C operating temperature range for dependable use in demanding industrial environments.

Key Advantages

• Space-saving triple-deck terminal block with three connection levels.
• 2.5 mm² rated cross-section for industrial signal and control wiring.
• Only 6 mm spacing helps maximise available DIN rail capacity.
• Blue housing supports clear circuit identification in complex panel assemblies.
• Ex e explosion-protected version for appropriately designed hazardous-area equipment.
• Three levels allow high wiring density without internally bridging the individual decks.
• Compatible with G32 and common TH35 DIN rail profiles.

Reliable High-Density Wiring for Industrial and Ex Applications

Triple-deck terminal blocks provide three connection levels within a single narrow terminal position, significantly increasing wiring density compared with conventional single-level designs. The D2.5/6-DA.N.EX therefore provides an efficient solution for control cabinets, instrumentation systems and junction boxes where available DIN rail length is limited.

Its Ex e design allows the terminal to be incorporated into appropriately certified hazardous-area equipment, while the polyamide housing and UL 94 V-0 flammability classification support demanding industrial installations. Compatibility with G32 and both common TH35 rail profiles also makes the terminal suitable for a broad range of existing and new panel designs.

Typical Applications

• Hazardous-area electrical assemblies.
• Industrial control and automation panels.
• High-density signal and control wiring.
• Instrumentation and process-control systems.
• Industrial junction and marshalling boxes.
• Machine-building electrical systems.
• Process, chemical and manufacturing installations.
• OEM control-panel and electrical equipment assemblies.
