Why Choose the TE Connectivity 1SNA299684R0200 D4/6.T3.P Triple-Deck Ground Terminal Block?

The TE Connectivity 1SNA299684R0200, also identified as D4/6.T3.P, is a grey 4 mm² triple-deck feed-through and ground terminal block from the Entrelec SNA screw-clamp range. Its multi-level construction combines three independent feed-through circuits plus a protective-earth connection within a compact 6 mm width, providing four independent circuits while conserving valuable DIN-rail space.

Designed for high-density industrial wiring, the D4/6.T3.P has an IEC rated current of 32 A, rated voltage of 500 V and impulse withstand voltage of 6 kV. Its screw-clamp connections accommodate rigid conductors from 0.2 to 4 mm² and flexible conductors from 0.22 to 4 mm², providing dependable termination for power, control and signal circuits.

The terminal uses a durable polyamide 6.6 housing with UL 94 V-0 flammability classification and provides IP20 protection at the main terminals. A closed terminal-block design eliminates the need for a separate end section, while compatibility with G32, TH35-7.5 and TH35-15 rails provides flexible integration into industrial control panels and distribution assemblies.

Key Advantages

• Three feed-through circuits plus protective earth provide four independent circuits in one compact terminal.
• Only 6 mm wide, helping maximise wiring density and reduce DIN-rail space requirements.
• 32 A IEC current rating supports demanding industrial control and distribution circuits.
• 500 V IEC voltage rating with 6 kV impulse withstand.
• Screw-clamp connections accept rigid and flexible conductors up to 4 mm².
• Closed terminal design requires no separate end section and improves assembly rigidity.

Key Features

• TE Connectivity / Entrelec D4/6.T3.P SNA terminal block.
• Triple-deck feed-through plus ground configuration.
• Four independent circuits within a 6 mm pitch.
• 4 mm² rated conductor size.
• Screw-clamp termination for secure industrial wiring.
• 480 A short-time withstand current for 1 s.
• IP20 protection at the main terminals.
• Grey polyamide 6.6 housing.
• UL 94 V-0 flammability classification.
• Mounting compatibility with G32, TH35-7.5 and TH35-15 rails.

Reliable Triple-Deck and Ground Connections in Minimal Rail Space

The D4/6.T3.P is engineered for applications where several circuits and protective-earth connections must be accommodated within a restricted panel footprint. By integrating three independent feed-through circuits and one ground circuit into a 6 mm-wide terminal, it significantly increases wiring density compared with using individual single-level terminals for each circuit.

Its proven screw-clamp system provides secure conductor retention, while the 32 A IEC rating, 500 V rated voltage and 480 A for 1 s short-time withstand capability support demanding industrial installations. The closed V0 polyamide housing and IP20 main-terminal protection further contribute to a robust, organised and space-efficient terminal assembly.

Typical Applications

• High-density industrial control panels.
• PLC and process-automation cabinets.
• Machine-building electrical systems.
• Combined signal, control and protective-earth wiring.
• Energy and industrial distribution equipment.
• Material-handling and transportation systems.
