1snk900107r0000 – cs-r3 circuit separator – dark grey

Why Choose the TE Connectivity CS-R3 Circuit Separator?

The TE Connectivity CS-R3 (1SNK900107R0000) is a dark grey circuit separator designed for use with ENTRELEC SNK Series PI-Spring terminal blocks. This insulating accessory provides physical and visual separation between circuit groups within DIN rail terminal assemblies, helping panel builders organise wiring clearly and maintain a professional terminal layout.

With a compact 3 mm spacing, the CS-R3 can be inserted between compatible PI-Spring terminal blocks without unnecessarily increasing the overall width of the terminal assembly. Its profile is designed specifically around the SNK PI-Spring terminal system, making it suitable for control panels, machinery, switchgear and industrial automation installations.

Manufactured from durable polyamide, the CS-R3 features a UL 94V-0 flammability rating and IP20 protection rating. It is suitable for operating temperatures from -55 to 110 °C, providing dependable performance across a broad range of industrial environments.

Clear Circuit Separation for PI-Spring Terminal Assemblies

Circuit separators provide a simple way to distinguish and physically separate groups of terminal blocks within an electrical assembly. This can improve the organisation of control-panel wiring and make individual circuit groups easier to identify during installation, inspection, troubleshooting and maintenance.

The CS-R3 is engineered for the ENTRELEC SNK PI-Spring terminal system and occupies only 3 mm of spacing within the assembly. Its insulating polyamide construction and robust temperature characteristics make it suitable for professional DIN rail installations in demanding industrial environments.

Typical Applications

• Industrial electrical control panels.
• PI-Spring DIN rail terminal block assemblies.
• Machine building and factory automation.
• Separation of individual circuit groups.
• Power distribution and control equipment.
• Process control and instrumentation systems.
• Switchgear and electrical cabinets.
• OEM machinery and panel building.
