The ABB DSE203NMC16A100 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 trusted ABB DSE203N M series, this compact protective device combines multiple safety functions into a single unit, making it an ideal solution for commercial, industrial and OEM electrical systems.
Designed to maximise electrical safety and installation efficiency, the DSE203NMC16A100 continuously monitors residual current while protecting circuits from overload and short-circuit conditions. By integrating residual current and overcurrent protection within one device, it reduces panel space requirements and simplifies installation whilst maintaining excellent system reliability.
With a 16 A Type C trip characteristic, 100 mA Type A residual current sensitivity and a 10 kA breaking capacity, the ABB DSE203NMC16A100 is ideally suited to protecting three-phase distribution circuits, machinery, automation equipment and industrial control systems. Its DIN rail mounted three-module construction enables fast installation within modern distribution boards and switchgear assemblies.
The ABB DSE203NMC16A100 combines miniature circuit breaker functionality with electronic residual current protection in a single compact device. This reduces installation complexity whilst providing dependable protection against overloads, short circuits and earth leakage faults across commercial and industrial electrical systems.
Its Type C tripping characteristic is well suited for circuits supplying motors, transformers and other equipment with moderate inrush currents. Combined with Type A residual current detection, it provides reliable protection for modern three-phase electrical installations.
