TE Connectivity 1SNA115936R0500 M4/8.D2.SFD3 is an 8 mm two-level screw-clamp fuse terminal block with two circuits, rated at 6.3 A and 500 V IEC for industrial signal and automation wiring.
£17.10
The TE Connectivity 1SNA115936R0500, also identified as M4/8.D2.SFD3, is a compact two-level screw-clamp fuse terminal block from the ENTRELEC SNA range. Designed for industrial signal circuits, control panels and automation equipment, it combines dependable conductor termination with integrated fuse functionality in a space-efficient DIN rail format.
The M4/8.D2.SFD3 features two circuits, four poles and two levels, allowing additional circuit functionality within an 8 mm-wide terminal body. Its screw-terminal connections provide secure, serviceable conductor termination, while the lever disconnect mechanism allows convenient access to the fused circuit during commissioning, troubleshooting and maintenance.
With an IEC rated current of 6.3 A, rated voltage of 500 V and nominal wire size of 4 mm², the 1SNA115936R0500 is engineered for industrial signal wiring. Its polyamide 6.6 housing, IP20 protection and compatibility with G32, TH 35-7.5 and TH 35-15 rails support reliable installation in demanding electrical cabinets.
Fuse terminal blocks combine conductor termination and circuit protection within a modular DIN rail assembly. This allows individual signal circuits to incorporate fuse protection directly at the terminal level while keeping wiring organised and accessible for inspection, fault finding and routine maintenance.
The M4/8.D2.SFD3 uses a two-level, two-circuit architecture to provide increased connection functionality without significantly increasing rail space. Its screw-clamp terminals and lever disconnect mechanism make it particularly suitable for industrial control systems where dependable connections and convenient circuit servicing are required.
