Why Choose the ABB DSE203NMB16A10 RCBO?
The ABB DSE203NMB16A10 is a compact and highly reliable 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) designed to protect three-phase electrical installations against overloads, short circuits and earth leakage faults. As part of the advanced ABB DSE203N M series, it combines multiple protection functions within a single three-module device, making it ideal for commercial, industrial and OEM electrical applications.
Designed for modern distribution systems, the DSE203NMB16A10 simplifies panel construction while delivering dependable protection for both equipment and personnel. Its electronic residual current detection, unswitched neutral and compact DIN rail mounted design allow straightforward installation inside electrical distribution boards and control panels.
With a 16 A Type B tripping characteristic, 10 kA breaking capacity and 10 mA Type A residual current sensitivity, the ABB DSE203NMB16A10 is suitable for protecting sensitive three-phase circuits requiring enhanced protection against electric shock and reliable fault interruption.

Reliable Protection for Three-Phase Electrical Systems
The ABB DSE203NMB16A10 continuously monitors electrical circuits for overloads, short circuits and earth leakage currents. If a fault is detected, the RCBO disconnects the circuit rapidly, helping protect electrical equipment, reduce downtime and improve safety for personnel.
Its Type B tripping characteristic is suitable for circuits supplying resistive loads and other equipment with relatively low inrush currents. The integrated 10 mA Type A residual current protection detects both AC and pulsating DC leakage currents, providing enhanced protection where increased electrical safety is required.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Machine building and OEM equipment.
- Three-phase power distribution.
- Manufacturing and automation systems.
- Critical circuits requiring enhanced residual current protection.
