1sna146031r1400 – d4/6,p,ado,ex
TE Connectivity 1SNA146031R1400 D4/6.P.ADO.Ex is a green/yellow 6 mm ADO ground terminal block with a 1.5 mm² rated cross-section, designed for compatible DIN rail installations in explosive atmospheres.
Why Choose the TE Connectivity 1SNA146031R1400 D4/6.P.ADO.Ex Ground Terminal Block?
The TE Connectivity 1SNA146031R1400, manufacturer designation D4/6.P.ADO.Ex, is a green/yellow ground terminal block from the Entrelec ADO connection range, specifically designed for use in compatible installations within explosive atmospheres. It combines an ADO connection system with protective-earth functionality for professional industrial wiring applications.
The D4/6.P.ADO.Ex has a rated cross-section of 1.5 mm² and a compact terminal spacing of 6 mm. Its ADO connection technology is designed to provide an efficient conductor connection while the ground-terminal configuration establishes the required connection to the mounting rail for protective-earth circuits.
Measuring approximately 50 mm high × 6 mm wide × 41 mm deep and weighing around 11 g, the terminal is compact enough for densely populated industrial panels. It mounts on TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715 and uses a polyamide insulating body suitable for operating temperatures from -55 to +110 °C.

Protective-Earth Connection for Explosive-Atmosphere Installations
Protective-earth terminal blocks provide a dedicated connection between field conductors and the equipment grounding system. The D4/6.P.ADO.Ex combines this grounding function with Entrelec ADO connection technology and a green/yellow housing, allowing protective-earth circuits to be clearly identified within industrial terminal assemblies.
The Ex version is specifically identified for use in compatible explosive-atmosphere applications and is included within the relevant ATEX-certified terminal block family. Correct installation must follow the applicable certification conditions, equipment documentation and hazardous-area requirements for the complete assembly.
Typical Applications
- Protective-earth connections in industrial control panels.
- Electrical equipment installed in compatible explosive-atmosphere environments.
- Process automation and instrumentation systems.
- Industrial machinery requiring dedicated protective-earth connections.
- DIN rail terminal assemblies in hazardous-area equipment.
- OEM panel building and maintenance of compatible Entrelec ADO installations.
