1SNA199339R0300 – FEDAD1 YELLOW END SECTION for ADO

Why Choose the TE Connectivity 1SNA199339R0300 FEDAD1 Yellow End Section?

The TE Connectivity 1SNA199339R0300, also known as the FEDAD1, is a yellow end section for Entrelec SNA ADO terminal blocks. Designed to complete and insulate compatible terminal block assemblies, it provides a neat and secure end closure for ADO-to-screw terminal installations in industrial control panels, machinery and automation systems.

The FEDAD1 is specifically designed for compatible SNA ADO feed-through and protective earth terminal blocks, including D2.5/5.ADO, D2.5/5.P.ADO, D4/6.ADO, D4/6.P.ADO, D6/8.ADO and D6/8.P.ADO types. Its snap-on construction simplifies assembly and helps maintain appropriate separation and insulation at the end of a terminal block group.

With a thickness of just 3 mm, the 1SNA199339R0300 provides the required terminal closure while adding minimal width to the DIN rail assembly. Its distinctive yellow colour enables clear visual identification, while the insulating material carries a UL94 V-0 flammability classification for use in professional electrical installations.

Professional End Closure for SNA ADO Terminal Assemblies

End sections are important accessories within modular terminal block installations because they close the exposed side of the final terminal and help maintain an organised, insulated assembly. The FEDAD1 is shaped specifically for compatible Entrelec SNA ADO terminals, providing a purpose-designed alternative to improvised panel separators or generic end plates.

Its slim 3 mm profile makes the FEDAD1 particularly suitable for densely populated industrial control cabinets where DIN rail space is valuable. The snap-on design also simplifies panel assembly, while the yellow construction allows the end section to be identified quickly during installation, inspection and maintenance.

Typical Applications

• Industrial electrical control panels.
• Entrelec SNA ADO terminal block assemblies.
• Machine building and OEM automation systems.
• PLC and process control cabinets.
• Factory automation equipment.
• Electrical distribution and interface panels.
• DIN rail installations requiring end closure for compatible ADO-to-screw terminals.
