Why Choose the ABB DSE203NMB13A10 RCBO?
The ABB DSE203NMB13A10 is a compact 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 systems. As part of the advanced ABB DSE203N M series, it integrates multiple protection functions into a single three-module device, making it ideal for commercial, industrial and OEM electrical installations.
Designed to simplify panel construction while improving electrical safety, the DSE203NMB13A10 features electronic residual current monitoring, an unswitched neutral and a compact DIN rail mounted design. Its robust construction and reliable operating characteristics make it suitable for demanding applications where dependable circuit protection is essential.
With a 13 A Type B tripping characteristic, 10 kA breaking capacity and 10 mA Type A residual current sensitivity, the ABB DSE203NMB13A10 is well suited to protecting three-phase circuits supplying resistive and low inrush current loads while providing enhanced protection against electric shock.

Reliable Protection for Three-Phase Electrical Systems
The ABB DSE203NMB13A10 continuously monitors circuits for overloads, short circuits and earth leakage faults. If a fault is detected, the RCBO disconnects the circuit rapidly, helping protect equipment, reduce downtime and improve electrical safety for personnel.
Its Type B tripping characteristic makes it particularly suitable for circuits supplying resistive loads and other equipment with relatively low inrush currents. The integrated 10 mA Type A residual current protection provides enhanced protection 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.
- Manufacturing and automation systems.
- Critical circuits requiring enhanced residual current protection.
