Why Choose the TE Connectivity HD185/36.F12.31.1M12 Stud Terminal Block?

The TE Connectivity HD185/36.F12.31.1M12, part number 1SNA295405R2700, is a heavy-duty feed-through stud terminal block designed for high-current industrial and railway electrical connections. It combines a robust M12 stud connection with a large conductor capacity, making it suitable for demanding power-distribution circuits where secure bolted terminations are required.

The terminal block uses a single M12 × 31.5 mm steel stud and is supplied with the associated connection hardware, including a bottom nut, two washers, a spring washer and a top nut. This bolted arrangement is intended for cable-lug connections and provides a mechanically secure interface for substantial conductors in vibration-prone and high-current environments.

With a rated cross-section of 185 mm², rated current of 353 A and rated voltage of 750 V AC/DC under the applicable NF C category, the HD185/36.F12.31.1M12 provides a high-capacity connection solution within a 36 mm pitch. It mounts on Type 2, TH 35-7.5 or TH 35-15 rails for integration into professional industrial and transport electrical assemblies.

High-Current Bolted Connections for Demanding Installations

Stud terminal blocks are used where high-current conductors terminated with cable lugs require a secure and mechanically robust electrical connection. The HD185/36.F12.31.1M12 uses an M12 stud and dedicated bolted hardware to clamp cable lugs firmly, helping maintain dependable electrical contact in industrial and railway applications.

Its 353 A current rating, large conductor capacity and compatibility with standard 35 mm mounting rails make it particularly suitable for high-power distribution assemblies. The 36 mm-wide format provides the mechanical space required for substantial cable lugs while retaining the modular installation benefits of a DIN rail terminal system.

Typical Applications

• Railway electrical and rolling-stock systems.
• High-current power distribution panels.
• Industrial switchgear and control cabinets.
• Heavy machinery electrical systems.
• Power conversion and distribution equipment.
• Large cable-lug termination points.
• OEM transport and industrial electrical assemblies.
