£13.28
The TE Connectivity 1SNA115143R1200, designated M70/31.FF, is a heavy-duty studded feed-through power terminal block from the ENTRELEC SNA Series. Designed for high-current industrial power distribution, it uses two M8 stud connections to provide secure cable-lug termination in electrical control panels, distribution assemblies and machinery.
With a rated current of 150 A and rated voltage of 1000 V, the M70/31.FF is engineered for demanding power circuits. Its stud connection accommodates rigid conductors from 2.5–70 mm² and flexible conductors from 2.5–50 mm², providing flexibility for a broad range of industrial power cabling requirements.
The terminal has a compact 31 mm spacing and measures approximately 66 × 31 × 51 mm (H × W × D). Its grey polyamide housing provides robust electrical insulation, while compatibility with G32, TH35-7.5 and TH35-15 DIN rails allows straightforward integration into standard industrial panel designs.
Studded power terminals are designed for circuits where secure termination of large power conductors is essential. The M70/31.FF uses two M8 studs for cable-lug connections, providing a robust feed-through interface suited to high-current circuits in control panels, distribution boards and industrial machinery.
Its 150 A current rating, 1000 V rated voltage and wide conductor capacity make the M70/31.FF suitable for demanding power distribution applications. DIN rail compatibility also allows the terminal to be incorporated alongside other modular components within ENTRELEC SNA terminal assemblies.
