Why Choose the TE Connectivity M4/8.SF2 Orange 1SNA105135R1100 Fuse Terminal Block?
The TE Connectivity M4/8.SF2 Orange 1SNA105135R1100 is a screw clamp fuse terminal block from the ENTRELEC SNA series, designed for protected signal wiring in industrial control panels, automation equipment and electrical distribution systems. Its integrated fuse function enables circuit protection to be incorporated directly into a modular DIN rail terminal assembly.
The M4/8.SF2 combines proven screw terminal connection technology with a lever-type disconnect arrangement, helping provide secure conductor termination together with practical access to the protected circuit. It has an IEC rated current of 6.3 A, an IEC rated voltage of 630 V and an 8 kV impulse withstand voltage.
With an 8 mm terminal spacing and compact dimensions of 56.5 × 8 × 41 mm, the 1SNA105135R1100 is well suited to organised control cabinet installations. Its distinctive orange Polyamide 6.6 housing assists visual identification, while compatibility with G32, TH35-15 and TH35-7.5 DIN rails provides installation flexibility across industrial panel designs.
