ECP35 Entrelec Circuit Seperator for M120/35… 1SNA113691R1600

The ECP35 (alternate code 1SNA113691R1600) is a grey circuit separator manufactured by TE Connectivity (Entrelec), designed for use with M120/35 stud terminal blocks on DIN rail assemblies.

The Entrelec ECP35 circuit separator provides a clean, physical division between circuit groups on stud terminal block installations. It slots directly into the terminal block rail assembly, allowing engineers to clearly segment circuits within a panel without the need for additional hardware. This makes wiring layouts easier to manage, identify, and maintain.

Key Features

• Compatible with M120/35 stud terminals: Specifically designed for M120/35.AF, M120/35.F, and M120/35.FF terminal blocks, ensuring a secure, precise fit without improvisation.
• Multi-rail mounting: Suitable for G32 (32 x 15 mm), TH35-7.5 (35 x 7.5 mm), and TH35-15 (35 x 15 mm) DIN rails to IEC 60715, giving flexibility across different panel builds.
• Grey colour coding: Standard grey finish integrates cleanly into existing panel layouts and makes circuit boundaries visually clear.
• Compatible with CPP35 protecting covers: Can be used alongside CPP35 covers, supporting a fully enclosed, organised terminal assembly.
• Lightweight construction: At just 10 g per piece, the ECP35 adds negligible weight to the rail assembly while providing a robust circuit boundary.
• Eco-designed product: Environmental information is documented under reference 1SND220090E1000, reflecting TE Connectivity's commitment to sustainable product development.

Applications

The ECP35 circuit separator is used in industrial control panels, switchgear, and power distribution assemblies where M120/35 stud terminals are installed. It is particularly suited to applications requiring clear visual and physical separation between circuit groups — such as power and control segregation, multi-circuit distribution panels, and large-format DIN rail assemblies common in manufacturing, infrastructure, and process automation environments.

Standards and Compliance

The ECP35 is classified under ETIM category EC000886 (Endplate and partition plate for terminal block) and is designed for use with terminal systems that conform to IEC 60715 rail standards.

Frequently Asked Questions

What terminal blocks is the ECP35 compatible with?

The ECP35 is specifically designed for use with M120/35.AF, M120/35.F, and M120/35.FF stud terminal blocks.

Which DIN rails does the ECP35 mount on?

It is compatible with G32 (32 x 15 mm), TH35-7.5 (35 x 7.5 mm), and TH35-15 (35 x 15 mm) mounting rails, all per IEC 60715.

Can the ECP35 be used with protecting covers?

Yes — the ECP35 can be used alongside CPP35 protecting covers for a fully enclosed terminal block assembly.

What is the difference between a circuit separator and an end section?

A circuit separator sits between terminal blocks to create a visible, physical boundary between circuit groups within a run, whereas an end section is fitted at the end of a terminal block group to close it off. The ECP35 is a circuit separator intended for mid-run circuit segregation on M120/35 stud terminals.
