Why Choose the TE Connectivity D4/6.ADO Feed-Through Terminal Block?
The TE Connectivity 1SNA199034R1500 D4/6.ADO is a compact and reliable grey feed-through terminal block designed for industrial control panels, machinery and electrical distribution systems. Part of the established ENTRELEC SNA ADO range, it combines the ADO connection system with a conventional screw clamp connection to provide flexible and dependable conductor termination.
The D4/6.ADO provides a rated current of 17.5 A and rated voltage of 1000 V, with a compact 6 mm pitch that helps maximise wiring density inside electrical cabinets. Its hybrid screw clamp and ADO configuration gives panel builders the benefits of the ADO system while retaining a familiar screw connection where required.
Designed for mounting on TH35-7.5 and TH35-15 DIN rails, the terminal accommodates rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm² on the screw-clamp connection. Its polyamide housing, IP20 main-terminal protection and broad operating temperature range make it well suited to demanding industrial installations.
