1SNA205429r0400 – schd2 circiut separator yellow

Why Choose the TE Connectivity 1SNA205429R0400 SCHD2 Circuit Separator?

The TE Connectivity 1SNA205429R0400, also identified as SCHD2, is a yellow insulating circuit separator designed for use with compatible screw-clamp terminal blocks. Part of the TE Connectivity / ENTRELEC terminal block accessory range, it provides additional physical and electrical separation between adjacent circuits within industrial terminal assemblies.

The SCHD2 separator has a compact thickness of 1.2 mm, allowing additional circuit separation to be incorporated without significantly increasing the overall width of a terminal block installation. Its distinctive yellow finish provides clear visual identification within control panels, switchgear and other electrical assemblies.

Designed as a dedicated accessory for ENTRELEC terminal systems, the 1SNA205429R0400 supports organised and professional panel construction. Its insulating construction makes it suitable for applications where adjacent terminal circuits require clear separation while retaining the modular advantages of rail-mounted terminal blocks.

Key Advantages

• Purpose-designed circuit separator for screw-clamp terminal blocks.
• Compact 1.2 mm thickness minimises additional installation width.
• Yellow colour provides clear visual identification within terminal assemblies.
• Insulating construction supports effective separation of adjacent circuits.
• Designed for compatible TE Connectivity / ENTRELEC terminal systems.
• Ideal for organised industrial control-panel and switchgear wiring.

Reliable Circuit Separation for Industrial Terminal Assemblies

Circuit separators are used within modular terminal block installations to increase physical separation between adjacent electrical circuits. The TE Connectivity SCHD2 provides a dedicated insulating barrier while adding only 1.2 mm to the terminal assembly, making it particularly useful where panel space and wiring organisation are important.

The SCHD2 is intended for compatible ENTRELEC screw-clamp terminal block configurations and provides panel builders with a straightforward way to separate circuits while retaining a neat modular installation. In specified terminal configurations where a jumper bar is installed, the corresponding spacer should be used instead of the circuit separator.

Typical Applications

• Industrial control panel terminal assemblies.
• Screw-clamp terminal block installations.
• Electrical circuit separation and organisation.
• Railway electrical and control systems.
• Power distribution and switchgear panels.
• Industrial machinery and automation cabinets.
