The TE Connectivity 1SNA146303R0200, also identified as D70/32,FF,Ex, is a heavy-duty stud feed-through terminal block from the Entrelec SNA range, designed for secure termination and distribution of high-current conductors in industrial electrical installations. Its robust stud connection system accommodates cable lugs and conductors with cross-sections from 6 to 70 mm².
Designed for demanding power distribution applications, the D70/32,FF,Ex has a 70 mm² rated cross-section and a 192 A rated current. The terminal uses stud connections at both sides and provides a tightening torque of 12 N·m for the cable lug and central bolt, helping deliver a mechanically secure and dependable electrical connection.
With a compact 32 mm spacing, grey housing and flexible mounting options, the 1SNA146303R0200 can be installed on G32, TH35-7.5 or TH35-15 mounting rails. The D70/32,FF,Ex series is also covered by ATEX certification for appropriate installations, making it suitable for specialised industrial environments when installed in accordance with the applicable certification requirements.
Stud terminal blocks provide a robust method of terminating large conductors fitted with suitable cable lugs. The bolted connection creates high mechanical clamping force and dependable electrical contact, making this terminal format particularly suitable for high-current distribution circuits, industrial machinery and power-control equipment.
The D70/32,FF,Ex combines a 70 mm² rated cross-section with a 192 A current rating and flexible rail mounting. Its high short-time withstand capability and robust stud construction make it a practical choice for demanding industrial electrical assemblies where secure high-current conductor termination is essential.
