ABB CS Polyamide Circuit Separator, DIN Rail Mount

The ABB CS Circuit Separator is a Polyamide-insulated endplate and partition device engineered to prevent the derating of terminal blocks when cut jumper bars (JB) are used. Compatible with feed-through terminal blocks up to 16 mm² / 4 AWG, it installs with 0 mm spacing loss, carries a V-0 flammability rating per UL94, and provides IP20 protection at the main terminals per IEC 60529. The unit mounts on standard DIN rail profiles and is finished in Dark Grey for clean integration into panel and terminal block assemblies.

Key Features

  • Wide Terminal Compatibility: Compatible with feed-through terminal blocks up to 16 mm² / 4 AWG, avoiding derating when cut jumper bars (JB) are used.
  • Zero Spacing Loss: Rated at 0 mm spacing, allowing installation without increasing overall terminal block run length.
  • Durable Insulation: Constructed from Polyamide insulation material rated V-0 per UL94 flammability standard.
  • DIN Rail Mounting: Mounts on G32 (32 x 15 mm), TH35-7.5 (35 x 7.5 mm), TH35-15 (35 x 15 mm), and TH15-5.5 (15 x 5.5 mm) mounting rails per IEC 60715.
  • Degree of Protection: Main terminals rated IP20 per IEC 60529, IEC 60947-1, and EN 60529.
  • Wide Operating Range: Rated for -55…+110°C ambient operation and storage.
  • Finish: Dark Grey color for consistent panel appearance.

Certifications & Compliance

  • Flammability Rated V-0 per UL94
  • RoHS Compliant per EU Directive 2002/95/EC (August 18, 2005) and amendments
  • Degree of Protection IP20 (Main Terminals) per IEC 60529, IEC 60947-1, EN 60529
  • Pollution Degree 3
  • Resistance to Vibrations Compliant per IEC 60068-2-6

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Terminal Block Assemblies in Industrial Control Panels
  • Feed-Through Terminal Block Separation Without Spacing Loss
  • Panelboard and Control Cabinet Wiring
  • DIN Rail Mounted Terminal Systems
  • Renovation and New Panel Construction

Why ABB?

ABB circuit separators combine Polyamide insulation rated V-0 per UL94 with a compact 0 mm spacing design, letting panel builders separate terminal circuits without derating terminal blocks or adding enclosure length. Backed by IEC-compliant degree-of-protection and vibration-resistance ratings, the CS Circuit Separator supports reliable, code-compliant terminal block assemblies for demanding industrial control environments, from feed-through terminal block runs to full panelboard and control cabinet wiring, delivering consistent Dark Grey panel integration and long service life across a wide -55…+110°C operating range.

ABB 1SNK900101R0000 – Frequently Asked Questions

1) What does an ABB CS circuit separator actually do in a terminal block run?
The ABB CS is an insulated endplate and partition that separates circuits within a DIN rail terminal block assembly. Its main job is preventing derating of the terminal blocks when cut jumper bars (JB) are used, so you can break a jumpered run into separate circuits and still keep the blocks at full rating. It is not a terminal, a fuse holder, or a disconnect.
2) What size terminal blocks does the ABB CS separator work with?
It suits feed-through terminal blocks up to 16 mm2 / 4 AWG. Above that conductor size it is outside the stated compatibility, so a larger frame separator is needed for heavier feed-through blocks.
3) Which DIN rail profiles does this ABB separator mount on?
Four profiles per IEC 60715: G32 (32 x 15 mm), TH35-7.5 (35 x 7.5 mm), TH35-15 (35 x 15 mm) and TH15-5.5 (15 x 5.5 mm). The common 35 mm top-hat rail in most control panels is covered in both the 7.5 mm and 15 mm depths.
4) Is the ABB CS separator rated for a hot or cold environment, like an outdoor pump house or a furnace room?
Ambient operating and storage range is -55 to +110 C, which covers unheated outdoor enclosures and hot equipment rooms alike. It also carries a vibration resistance rating per IEC 60068-2-6, so it holds up in machinery and skid-mounted panels.
5) What is the ABB part number and color for this circuit separator, so I can match what is already in my panels?
The order number is 1SNK900101R0000 and the finish is dark grey, which matches the standard grey used across ABB terminal block accessories for a consistent look down the rail. Ordering by that number gets the same item every time when you are standardizing panel builds across a facility.
6) Do I need a separator if I am cutting jumper bars between terminal blocks?
Cutting a jumper bar leaves an exposed cut end and an unguarded boundary between circuits, and that is the condition the CS separator is built for: it sits at the break so the blocks are not derated and the adjacent circuit stays partitioned. Made of polyamide, it insulates rather than just spacing the blocks apart.
