Why Choose the ABB DSE203NMC10A10 RCBO?
The ABB DSE203NMC10A10 is a compact 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) engineered to provide comprehensive protection against overloads, short circuits and earth leakage faults in three-phase electrical systems. As part of the advanced ABB DSE203N M series, it combines multiple protective functions into a single space-saving device, making it ideal for commercial, industrial and OEM applications.
Designed to simplify installation and improve electrical safety, the DSE203NMC10A10 incorporates electronic residual current monitoring with an unswitched neutral configuration. Its compact three-module design allows panel builders and electrical contractors to maximise space within distribution boards while maintaining reliable circuit protection.
With a 10 A Type C tripping characteristic, 10 kA breaking capacity and 10 mA Type A residual current sensitivity, the ABB DSE203NMC10A10 is well suited to protecting three-phase circuits supplying equipment with moderate inrush currents while providing enhanced protection against electric shock.

Reliable Protection for Three-Phase Installations
The ABB DSE203NMC10A10 continuously monitors circuits for overloads, short circuits and earth leakage faults. When abnormal conditions occur, the RCBO disconnects the affected circuit quickly to help protect electrical equipment, minimise downtime and improve user safety.
Its Type C operating characteristic makes it suitable for circuits supplying motors, control equipment and other loads with moderate inrush currents. The integrated 10 mA Type A residual current protection provides enhanced protection against electric shock by detecting both AC and pulsating DC leakage currents.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Machine building and OEM equipment.
- Three-phase power distribution.
- Automation and manufacturing systems.
- Critical circuits requiring enhanced residual current protection.
