Why Choose the TE Connectivity HD2.5/6.3.GG.1.2GG Quick-Connect Terminal Block?
The TE Connectivity HD2.5/6.3.GG.1.2GG (1SNA199025R1400) is a compact three-circuit quick-connect terminal block designed for efficient wiring in industrial and railway electrical systems. Part of the established TE Connectivity ENTRELEC SNA HD range, it provides six flat-tab connections in a space-saving terminal body for reliable connection of control, signalling and auxiliary circuits.
This terminal block incorporates three electrically separate circuits, each equipped with two longitudinal quick-connect tabs. The 6.3 × 0.8 mm flat-tab interface allows compatible female quick-connect terminals to be fitted rapidly without conventional screw termination, helping reduce wiring and maintenance time in equipment where repeated connections or efficient assembly are important.
With a compact 6 mm spacing, a rated voltage of 250 V and rated current of 25 A, the HD2.5/6.3.GG.1.2GG combines high connection density with dependable electrical performance. Its green thermoplastic insulating body has a UL 94V-0 flammability classification and is suitable for operating temperatures from -55 to +110 °C.

Reliable Multi-Circuit Quick-Connect Wiring
Quick-connect terminal blocks use standardised flat tabs to create detachable electrical connections without requiring a screw to be tightened for every conductor. This can significantly simplify production wiring and servicing, particularly in equipment where harnesses and individual circuits need to be connected or disconnected efficiently.
The TE Connectivity HD2.5/6.3.GG.1.2GG places three independent circuits within a 6 mm-wide terminal, providing two longitudinal 6.3 × 0.8 mm tabs for each circuit. The upper circuit also supports testing and transverse connection, while jumper-bar installation can be accommodated by removing the relevant precut partition.
Typical Applications
- Railway electrical and signalling equipment.
- Industrial control and automation panels.
- Multi-circuit control wiring.
- Machine and equipment wiring harnesses.
- PLC and instrumentation cabinets.
- Transport and infrastructure electrical systems.
- OEM machinery and industrial panel building.
