The ABB DSE203NMC6A10 is a high-performance 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) designed to provide comprehensive protection against overloads, short circuits and earth leakage faults in three-phase electrical installations. Part of the advanced ABB DSE203N M series, it combines multiple protection functions within a compact three-module device for modern commercial and industrial distribution systems.
Designed for reliability and ease of installation, the DSE203NMC6A10 offers dependable circuit protection while helping minimise downtime and improving electrical safety. Its electronic residual current detection, unswitched neutral and compact DIN rail design make it an excellent choice for panel builders, electrical contractors and OEM applications.
With a 6 A Type C tripping characteristic, 10 kA breaking capacity and 10 mA Type A residual current sensitivity, the ABB DSE203NMC6A10 is ideal for protecting sensitive three-phase circuits requiring enhanced personnel protection and reliable fault discrimination.
The ABB DSE203NMC6A10 combines overcurrent and residual current protection into a single compact device, helping simplify panel design while improving installation efficiency. By detecting overloads, short circuits and earth leakage currents, it protects electrical equipment and personnel while supporting compliance with modern wiring regulations.
Its Type C characteristic makes it particularly suitable for circuits supplying equipment with moderate inrush currents, while the highly sensitive 10 mA residual current protection provides enhanced safety in applications where additional protection is required.
