Why Choose the TE Connectivity 1SNA168500R1200 PR4 CENELEC DIN Rail?
The TE Connectivity 1SNA168500R1200, designated PR4, is a heavy-duty TH35-15 symmetrical mounting rail designed for mounting compatible terminal blocks and other DIN rail components in industrial electrical installations. Manufactured from zinc-plated and passivated steel, it provides a robust mechanical mounting platform for control panels, distribution assemblies and automation systems.
The PR4 follows the 35 × 15 mm top-hat rail format and complies with IEC 60715. Each rail is supplied in a 2 m length, providing ample mounting space for larger terminal assemblies while allowing the rail to be cut to suit individual panel layouts.
The PR4 is particularly recommended for SNK protective-earth terminal blocks up to 35 mm² / 2 AWG. Its steel construction also provides an equivalent copper cross-section of 50 mm² / 2 AWG, making it suitable for applications where the mounting rail forms part of the protective-earth arrangement in accordance with the applicable terminal-system requirements.

Robust TH35-15 Mounting for Industrial Terminal Systems
DIN mounting rails provide a standardised mechanical platform for arranging terminal blocks and other modular electrical components inside industrial enclosures. The TH35-15 profile combines the familiar 35 mm top-hat format with a deeper 15 mm section, providing a robust mounting base for demanding terminal installations.
The PR4's zinc-plated and passivated steel construction makes it suitable for professional panel building and terminal assemblies. When used with compatible protective-earth terminals, its specified equivalent copper cross-section also enables the rail to support the electrical continuity requirements of the intended grounding system.
Typical Applications
- Industrial electrical control panels.
- Entrelec SNA and SNK terminal block assemblies.
- Protective-earth terminal installations.
- Electrical distribution cabinets.
- Machine and automation control systems.
- OEM equipment and professional panel building.
