Why Choose the TE Connectivity HD120/30.F10.31 1SNA295448R0100 M10 Stud Terminal Block?

The TE Connectivity HD120/30.F10.31 1SNA295448R0100 is a heavy-duty 120 mm² feed-through stud terminal block designed for high-current power connections in demanding industrial and railway electrical systems. Part of the established TE Connectivity / Entrelec SNA HD range, it combines a robust M10 bolted connection with DIN rail mounting for secure termination of large conductors fitted with suitable cable lugs.

The terminal incorporates a single M10 × 31.5 mm stud equipped with an H130 self-locking nut, TREP 3L spring washer and washer. This mechanically secure termination arrangement is designed to maintain dependable conductor contact in applications where high current, vibration and demanding operating conditions require a substantial bolted connection.

With a 120 mm² rated cross-section, 269 A rated current and 750 V AC/DC rated voltage, the HD120/30.F10.31 is suited to substantial power-distribution circuits. Its 30 mm nominal spacing, beige insulating housing and compatibility with Type 2, TH35-7.5 and TH35-15 rails support integration into modular high-power terminal assemblies.

Heavy-Duty Stud Connections for High-Current Circuits

Stud terminal blocks provide a robust termination method for large conductors fitted with suitable cable lugs. The lug is secured directly to a threaded stud using a nut and washer assembly, creating a mechanically strong electrical interface suited to high-current circuits and equipment exposed to vibration or demanding service conditions.

The HD120/30.F10.31 combines an M10 stud connection with conductor capacities up to 120 mm² and a 269 A rated current. This makes it particularly suitable for substantial power connections where conventional small screw or spring terminals would not provide the required conductor capacity or mechanical connection strength.

Typical Applications

• Industrial high-current power distribution panels.
• Railway and transportation electrical systems.
• Heavy machinery and OEM electrical equipment.
• Switchgear and distribution cabinets.
• Large-conductor feed-through connections.
• Power supply and common-potential circuits.
• DIN rail assemblies requiring secure high-current cable-lug termination.
