Why Choose the ABB DSE203NMB16A100 RCBO?

The ABB DSE203NMB16A100 is a premium 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO), engineered to provide dependable protection against overloads, short circuits and earth leakage faults in three-phase electrical installations. As part of the proven ABB DSE203N M series, this compact protective device integrates multiple safety functions into a single unit, making it an excellent solution for commercial, industrial and OEM electrical systems.

Designed to improve electrical safety and installation efficiency, the DSE203NMB16A100 continuously monitors residual current whilst protecting circuits from overload and short-circuit conditions. Combining residual current and overcurrent protection in one device reduces panel space requirements, simplifies wiring and helps improve overall system reliability.

Featuring a 16 A Type B trip characteristic, 100 mA Type A residual current sensitivity and a 10 kA breaking capacity, the ABB DSE203NMB16A100 is ideally suited for protecting three-phase distribution systems, machinery, automation equipment and industrial control panels. Its compact three-module DIN rail mounted construction allows straightforward installation in modern electrical enclosures.
