DS301C Range

Slimmer size, biggest protection

Discover ABB’s new range of RCBOs in a single module width only. This new range covers the increasing worldwide need to protect circuits in a compact electrical protection board. Furthermore, this range offers free space to welcome future devices such as home automation.

In addition to the existing DS201 (2019) RCBO series (2 modules width), ABB is introducing this new generation of RCBO called DS301C (1 module width) for space-related applications.

This new product is the perfect combination of MCB Unibis and ABB RCCB technologies. It guarantees, as a RCBO, to protect each circuit individually from overload to protect installation, fault default for human protection and continuity of service for the other circuits.

With this new DS301C, ABB can cover the main market needs for residential, commercial and building applications up to 20 A rating nominal current.

Main features

  • 1 module with (17.6mm), same as MCB SN201 series
  • From 6 to 20 A rated current
  • Icn 6kA, IΔn 30mA, B+C, A+AC to cover the main needs

Main benefits


Space saving
Being twice as compact in comparison to the conventional RCBO DS201 or RCCB+MCB combination, the new range offers reduced enclosure size or extended circuits protection.


Continuity of service
When a circuit is reporting an issue, a simple disconnection will provide you the details on the DTI window and the CPI indication. A quick win to speed up the maintenance. 


Easy to install
Thanks to the ease of mounting the device on a DIN rail, the clear terminals identification and compatibility with the busbar the installation time is limited.
