Why Choose the TE Connectivity HD2.5/6.3.2G.2G.1 Terminal Block?
The TE Connectivity HD2.5/6.3.2G.2G.1 is a compact double-deck feed-through terminal block designed for reliable electrical connections in railway applications, industrial control panels and automation systems. Part of the ENTRELEC SNA HD range, it uses quick-connect flat-tab technology to provide efficient wiring while making good use of available panel space.
The HD2.5/6.3.2G.2G.1 provides two levels with four longitudinal quick-connect tabs and a 6 mm terminal spacing. Each connection uses a 6.3 × 0.8 mm quick-connect tab, providing a practical alternative to conventional screw-clamp terminal connections in suitable applications.
With a 2.5 mm² rated cross-section, 25 A rated current and 250 V rated voltage, the 1SNA190305R0500 is designed for compact wiring installations. Its beige thermoplastic body has a UL 94 V-0 flammability rating and supports mounting on 35 mm DIN rail systems.
Key Advantages
- Compact double-deck feed-through terminal block for high-density wiring.
- 25 A rated current for suitable industrial and railway electrical circuits.
- 250 V rated voltage for compatible control and distribution applications.

Efficient Quick-Connect Wiring for Industrial Applications
Quick-connect terminal blocks provide a fast and reliable method of connecting conductors using standardised flat tabs. The HD2.5/6.3.2G.2G.1 uses four longitudinal 6.3 × 0.8 mm tabs across its two levels, providing an efficient wiring solution where rapid connection and compact installation are important.
The double-deck arrangement places two connection levels within a compact 6 mm pitch footprint, helping increase terminal density on 35 mm DIN rail. The design also permits testing and transverse connection, while jumper bars can be used where the pre-cut partition is removed as specified by the manufacturer.
Typical Applications
- Railway electrical equipment and rolling stock applications.
- Industrial electrical control panels.
- PLC and automation control systems.
- Machine control cabinets.
- High-density electrical wiring assemblies.
- Industrial transportation and control equipment.
