Why Choose the TE Connectivity 1SNA190008R0700 D120/42.AF Power Terminal?
The TE Connectivity 1SNA190008R0700, identified as the D120/42.AF, is a heavy-duty 120 mm² feed-through power terminal block from the Entrelec SNA range. Designed for high-current industrial connections, it combines an M10 stud connection with a screw wire-clamp connection to provide a robust interface between large power conductors.
The D120/42.AF has a 42 mm pitch and a maximum contact current rating of 269 A. Its conductor capacity includes rigid solid or stranded conductors from 6 mm² to 150 mm² and flexible conductors from 6 mm² to 120 mm², making it suitable for demanding power distribution and machine-building installations.
Supplied with protection covers, the terminal provides IP20 protection when correctly assembled. Its two-position holding foot supports convenient mounting on standard TH35 DIN rail, while provision for rail or base mounting and compatible lug connections gives panel builders flexibility when constructing high-current electrical systems.
