The TE Connectivity D70/22.YL, part number 1SNA400789R0000, is a heavy-duty screw clamp feed-through terminal block designed for secure power conductor termination in industrial electrical panels and distribution systems. Part of the ENTRELEC SNA terminal block range, this yellow DIN rail terminal combines high-current capability with robust screw-terminal connections for demanding industrial installations.
Designed for power circuits, the D70/22.YL has an IEC current rating of 192 A and an IEC voltage rating of 1000 V. Its screw-clamp termination system provides firm mechanical retention and reliable electrical contact, while the single-level feed-through configuration enables straightforward connection of incoming and outgoing power conductors.
The terminal accommodates flexible conductors from 16–70 mm² and rigid stranded conductors from 16–95 mm². With a 22 mm product spacing, yellow polyamide 6.6 housing and compatibility with TH35 DIN rails, the D70/22.YL is well suited to industrial switchboards, machinery, distribution assemblies and control cabinets.
Feed-through terminal blocks provide a secure and organised method of joining conductors within electrical panels and power distribution assemblies. The TE Connectivity D70/22.YL uses a screw-clamp termination system to maintain firm conductor contact, making it suitable for high-current circuits where dependable electrical continuity and mechanical retention are essential.
Its broad conductor capacity and standard DIN rail mounting format make the D70/22.YL particularly suitable for industrial power distribution and machinery applications. The combination of a 192 A IEC current rating, 1000 V rating and 8400 A one-second short-time withstand capability provides robust electrical performance for demanding power connections.
