Why Choose the TE Connectivity D35/27.FF.Ex 1SNA146302R0100 Stud Terminal Block?

The TE Connectivity D35/27.FF.Ex 1SNA146302R0100 is a heavy-duty 35 mm² stud feed-through terminal block from the Entrelec SNA range, designed for secure high-current conductor connections in industrial electrical panels, machinery and power distribution systems. Its robust stud connection technology is particularly suited to conductors terminated with cable lugs where dependable mechanical retention is essential.

Rated at 125 A, the D35/27.FF.Ex accepts flexible conductors from 2.5–35 mm² and rigid conductors from 2.5–50 mm². The terminal also provides a rated short-time withstand current of 4200 A for 1 s, making it a capable connection point for demanding industrial power circuits.

The grey polyamide terminal has a 27 mm spacing and measures approximately 163 × 27 × 75 mm. It mounts on standard TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715 and operates across a broad temperature range of -55 to +110 °C, supporting reliable installation in demanding industrial environments.

Robust Stud Connections for High-Current Circuits

Stud terminal blocks are designed for power circuits where conventional small screw-clamp terminals may not provide the required conductor capacity or mechanical connection format. The D35/27.FF.Ex accommodates cable-lug connections and combines a 35 mm² rated cross-section with a 125 A current rating, providing a robust interface for industrial power distribution.

The terminal's high-strength connection arrangement, 27 mm pitch and standard TH35 rail mounting make it straightforward to integrate into modular power assemblies. Compatible accessories are available within the Entrelec SNA system, including protective covers and jumper bars, allowing panel builders to configure organised high-current terminal groups for specific applications.

Typical Applications

• Industrial power distribution panels.
• High-current DIN rail conductor connections.
• Machine and production-line electrical cabinets.
• Motor control and power distribution systems.
• Switchgear and industrial control assemblies.
• Cable-lug termination within electrical panels.
