Why Choose the TE Connectivity 1SNA115190R1600 M4/6.G Grey Feed-Through Terminal Block?
The TE Connectivity 1SNA115190R1600, type M4/6.G, is a grey 4 mm² specific feed-through terminal block from the Entrelec SNA range. Designed for industrial electrical connections, it combines quick-connect and screw-clamp technology in a compact 6 mm-wide housing for control panels, machinery, automation systems and specialised wiring assemblies.
The M4/6.G has a rated cross-section of 4 mm² and accepts flexible or rigid conductors from 0.5–4 mm² at its screw-clamp connection. Its feed-through configuration provides a single electrical circuit on one level, while the quick-connect interface allows integration with the corresponding flat-connection system.
Rated at 25 A and 750 V, the 1SNA115190R1600 is designed for professional industrial wiring. It mounts on G32, TH35-7.5 and TH35-15 rails, offers a short-time withstand current of 480 A for 1 s, and operates across a broad -55 to +110 °C temperature range.

Compact Quick-Connect Feed-Through Wiring
The M4/6.G provides a specialised feed-through connection within the Entrelec SNA terminal system. Its combination of quick-connect and screw-clamp technology enables a conventional stripped conductor to be securely terminated while providing the corresponding quick-connect interface required by the application, making it useful where detachable or specialised connections are needed within an industrial panel.
With a 4 mm² rated cross-section, 25 A current rating and only 6 mm of terminal width, the TE Connectivity 1SNA115190R1600 provides useful electrical capacity without consuming excessive DIN rail space. Compatibility with both G32 and TH35 rails also supports installation in new equipment and maintenance of established Entrelec terminal assemblies.
The 1SNA115190R1600 is the Entrelec M4/6.G grey specific feed-through terminal block, featuring a 4 mm² rated cross-section and quick-connect / screw-clamp connection technology.
