Why Choose the TE Connectivity 1SNA190009R0000 D185/55.AF Power Terminal?
The TE Connectivity 1SNA190009R0000 is a D185/55.AF high-current feed-through power terminal block designed for demanding industrial power distribution applications. Part of the established Entrelec SNA terminal block range, it combines a screw-clamp connection with an M12 stud connection to provide a robust transition point for large conductors and cable lugs.
Designed around a rated cross-section of 185 mm², the D185/55.AF supports rigid conductors up to 240 mm² on its screw-clamp connection and is rated for a main-circuit current of 353 A. Its 55 mm spacing and substantial construction make it suitable for high-current circuits where secure conductor termination and dependable mechanical retention are essential.
The terminal features IP20 protection covers and can be mounted on compatible DIN rail or base-mounted arrangements. A two-position holding foot assists DIN rail installation, while the stud connection supports cable-lug mounting in accordance with established industrial connection practices, making the 1SNA190009R0000 well suited to switchgear, machinery and power distribution assemblies.
