DS301C Range

Slim, space-saving, voltage independent RCBOs for next-level safety

Discover ABB’s DS301C RCBO Slim, space-saving, voltage independent RCBOs for next-level safety! 
Did you know? DS301C is the slimmest RCBO that ABB has ever made which conforms to EN / IEC 61009-2-1.  
ABB presents the DS301C, a new generation of RCBOs in a single module width, designed to meet the growing global demand for compact circuit and people protection. Its slim design frees up space in the electrical board, making room for future technologies like home automation.
Complementing the existing DS201 series (2 modules, launched in 2019), the DS301C is ideal for space-constrained applications in residential, commercial, and building environments, supporting up to 20 A nominal current.
Combining ABB’s MCB and RCCB technologies, the DS301C offers:

  • Overload protection for installation safety,
  • Fault current protection for human safety,
  • Continuity of service for unaffected circuits.

The DS301C is a voltage-independent (electromechanical) RCBO, meaning it operates reliably even without supply voltage, critical for fault detection and user protection.
 
To ensure safety and regulatory compliance, always verify that RCBOs conform to IEC / EN 61009-2-1. This standard defines the requirements for RCBOs used in households and similar applications and mandates the use of voltage-independent devices for dependable protection.

Main benefits

space saving
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.

around service
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.
