1sna295402r2400 – hd70/22.f8.31.2 m8 stud

Why Choose the TE Connectivity HD70/22.F8.31.2 1SNA295402R2400 M8 Stud Terminal Block?

The TE Connectivity 1SNA295402R2400, manufacturer designation HD70/22.F8.31.2, is a heavy-duty M8 stud feed-through terminal block designed for high-current power connections in demanding industrial and railway electrical systems. Part of the established TE Connectivity ENTRELEC stud terminal block range, it combines robust bolted termination with DIN rail mounting for secure connection of large lug-terminated conductors.

The HD70/22.F8.31.2 features a brass M8 × 31.5 mm stud assembly equipped with one bottom nut, two washers, one spring washer and one top nut. This arrangement provides strong mechanical retention and dependable electrical contact, making the terminal particularly suitable for power circuits where vibration resistance, high current capacity and long-term connection integrity are important.

With a rated conductor size of 70 mm², a rated current of 192 A and an NFC voltage rating of 750 V AC/DC, the 1SNA295402R2400 is engineered for substantial power distribution requirements. Its beige housing, 22 mm terminal width and compatibility with reinforced Type 2 and TH35 DIN rails make it a practical choice for industrial equipment, transportation systems and railway electrical assemblies.

Robust High-Current M8 Stud Connections

Stud terminal blocks are designed for applications where large conductors are terminated with cable lugs and a mechanically secure connection is essential. The HD70/22.F8.31.2 uses a brass M8 × 31.5 mm stud with a bottom nut, two washers, spring washer and top nut, providing a robust bolted interface for high-current power conductors.

Its 192 A current rating and support for NFC tubular lugs from 6–70 mm² make the 1SNA295402R2400 particularly suitable for substantial power distribution circuits. The terminal can be mounted on Type 2 reinforced rail as well as TH35-7.5 and TH35-15 DIN rails, allowing it to be incorporated into organised industrial and railway terminal assemblies.

Typical Applications

• High-current industrial power distribution panels.
• Railway and transportation electrical systems.
• Machine building and heavy industrial equipment.
• Power circuits using lug-terminated conductors.
• Control and distribution cabinets requiring high-current connections.
• DIN rail power terminal and distribution assemblies.
