Why Choose the TE Connectivity SCMA5D 1SNA116720R2100 Circuit Separator?
The TE Connectivity SCMA5D 1SNA116720R2100 is a purpose-designed grey circuit separator for compatible ENTRELEC SNA screw clamp terminal blocks. It provides additional electrical separation within assembled terminal strips, helping panel builders organise and isolate groups of circuits while maintaining a compact DIN rail installation.
Designed for compatible M2.5/5.D double-deck terminal blocks, the SCMA5D snaps onto the top of the terminal block after the terminal assembly has been constructed. Unlike a conventional partition plate inserted between terminals, this circuit separator is designed so that it does not increase the overall thickness of the terminal block assembly, making it particularly useful in space-constrained control cabinets.
The SCMA5D is part of the established TE Connectivity ENTRELEC SNA accessory range and is suitable for screw clamp terminal block installations operating from -55 to +110 °C. Its simple snap-on installation makes it a practical accessory for industrial control panels, automation equipment, instrumentation systems and other professional DIN rail terminal assemblies.
Key Advantages
- Purpose-designed circuit separator for compatible ENTRELEC SNA screw clamp terminal blocks.
- Snaps directly onto the top of the assembled terminal block for straightforward installation.
- Does not increase terminal block thickness, helping preserve DIN rail space.
- Provides clear physical separation between selected circuits or terminal groups.
- Wide -55 to +110 °C operating temperature range for demanding industrial environments.
- Suitable for professional control panel, machinery and automation terminal assemblies.
Key Features
- TE Connectivity / ENTRELEC SNA insulating accessory.
- SCMA5D circuit separator.
- Designed for compatible M2.5/5.D double-deck terminal blocks.
- Compatible with screw clamp terminal blocks.
- Top-mounted snap-on installation.

- Suitable for operating temperatures from -55 to +110 °C.
Compact Circuit Separation for DIN Rail Terminal Assemblies
Circuit separators are used within terminal strips to provide a clear physical division between selected electrical circuits or functional groups. The TE Connectivity SCMA5D is designed to snap onto the top of compatible double-deck terminal blocks once the terminal board has been assembled, making it easy to introduce separation exactly where it is required.
Because the SCMA5D does not add to the terminal block pitch, it provides circuit separation without consuming additional DIN rail width. This makes it particularly useful in densely populated control cabinets where circuits need to be clearly organised while available panel space is limited.
Typical Applications
- Industrial control panel terminal assemblies.
- M2.5/5.D double-deck terminal block installations.
- Separation of different circuit groups within terminal strips.
- PLC, automation and instrumentation wiring.
- Machine building and OEM electrical cabinets.
- DIN rail terminal assembly, refurbishment and maintenance.

Frequently Asked Questions
What is the TE Connectivity SCMA5D 1SNA116720R2100 used for?
The SCMA5D is a circuit separator used to provide physical and insulating separation between selected circuits or groups of compatible ENTRELEC SNA screw clamp terminal blocks.
Which terminal blocks are compatible with the SCMA5D?
The SCMA5D is designed for compatible M2.5/5.D double-deck screw clamp terminal blocks in the ENTRELEC SNA terminal block range.
How is the SCMA5D circuit separator installed?
The SCMA5D is designed to snap onto the top of the compatible terminal block after the terminal strip has been assembled, providing straightforward installation without disturbing the connected conductors.
Does the SCMA5D increase the width of the terminal block assembly?
No. The SCMA5D is designed to fit on top of the terminal block and therefore requires 0 mm additional spacing, helping maintain a compact DIN rail assembly.
What is the operating temperature range of the SCMA5D?
The TE Connectivity SCMA5D is specified for an operating temperature range of -55 to +110 °C, making it suitable for a broad range of industrial environments.
