The TE Connectivity 1SNA299683R0100, also identified as D4/6.T3, is a grey 4 mm² triple-deck screw-clamp terminal block from the Entrelec SNA range. Its three-level design provides three independent feed-through circuits within a compact 6 mm width, helping panel builders achieve high wiring density without increasing the length of the DIN-rail assembly.
Designed for industrial control and distribution applications, the D4/6.T3 is rated at 32 A and 500 V, with a rated impulse withstand voltage of 6 kV and a short-time withstand current of 480 A for 1 s. Its screw-clamp connections accommodate rigid conductors from 0.2 to 4 mm² and flexible conductors from 0.22 to 4 mm².
The terminal uses a flame-retardant polyamide 6.6 housing with UL 94 V-0 classification and provides IP20 protection at the main terminals. Compatibility with G32, TH35-7.5 and TH35-15 mounting rails makes the D4/6.T3 a versatile solution for compact industrial terminal assemblies.
The D4/6.T3 is designed to increase circuit density by stacking three electrically independent feed-through levels within a terminal only 6 mm wide. This arrangement can significantly reduce the amount of DIN-rail space required compared with installing three separate single-level terminals, making it particularly useful in densely populated control cabinets.
Proven screw-clamp termination provides secure conductor retention, while the 32 A rating, 500 V operating capability and 480 A for 1 s short-time withstand rating support demanding industrial wiring. The closed housing, IP20 protection and flame-retardant insulation further contribute to a robust and organised terminal assembly.
