Why Choose the TE Connectivity 1SNA115535R0300 D2.5/6.DAL Terminal Block?

The TE Connectivity 1SNA115535R0300, also identified as D2.5/6.DAL, is a compact three-level feed-through screw-clamp terminal block designed for high-density power and signal wiring in industrial control panels, automation systems and electrical equipment. Part of the established TE Connectivity / Entrelec SNA series, it combines six connection positions with a narrow DIN-rail footprint for efficient panel wiring.

The D2.5/6.DAL provides three connection levels and six positions, allowing multiple circuits to be arranged vertically while reducing the amount of DIN-rail length required. Proven screw-terminal technology provides secure conductor retention, while the polyamide housing offers robust insulation for demanding industrial environments.

With an IEC rated current of 22 A, IEC rated voltage of 380 V and conductor capacity up to 2.5 mm², the 1SNA115535R0300 is well suited to compact power and signal distribution. Its 6 mm width and compatibility with TH35-7.5 and TH35-15 DIN rails make it particularly useful for densely populated control cabinets.

High-Density Power and Signal Connectivity

Three-level terminal blocks enable several electrical circuits to be arranged vertically within a compact DIN-rail footprint. The D2.5/6.DAL provides six screw-terminal positions across three levels, making it an effective solution for applications where numerous power or signal conductors must be terminated while conserving valuable panel space.

Its screw-clamp system provides secure electrical contact and strong conductor retention, while the 6 mm profile allows terminals to be installed at high density. The robust polyamide housing and broad operating-temperature range make the 1SNA115535R0300 suitable for demanding machinery, automation and process-control environments.
