Why Choose the ABB DSE203NMC16A10 RCBO?
The ABB DSE203NMC16A10 is a compact and dependable electronic residual current circuit breaker with overcurrent protection (eRCBO) designed to protect three-phase electrical circuits against overloads, short circuits and earth leakage faults. As part of the ABB DSE203N M series, it combines residual current and overcurrent protection within a single DIN rail device, helping simplify electrical distribution-board design and reduce panel space requirements.
This RCBO is suitable for commercial, industrial and machine-building installations where reliable fault protection is essential. Its electronic residual current monitoring supports accurate leakage-current detection, while the 3P+N configuration enables comprehensive protection of three-phase circuits incorporating a neutral conductor.
With a rated current of 16 A, a Type C tripping characteristic, 10 mA Type A residual current sensitivity and a 10 kA short-circuit breaking capacity, the ABB DSE203NMC16A10 is well suited to circuits supplying equipment with moderate starting currents while providing enhanced protection against electric shock.

Reliable Protection for Three-Phase Electrical Circuits
The ABB DSE203NMC16A10 monitors the protected circuit for excessive current and leakage to earth. When an overload, short circuit or residual current fault occurs, the RCBO disconnects the affected circuit to help reduce the risk of equipment damage, electrical fire and electric shock.
Its Type C operating characteristic is suitable for circuits supplying equipment with moderate inrush currents, including selected motors, lighting systems, control equipment and industrial machinery. The sensitive 10 mA residual current threshold provides enhanced additional protection where a lower leakage-current trip level is required.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control and automation panels.
- Three-phase lighting and power circuits.
- Machine building and OEM equipment.
- Manufacturing and processing facilities.
- Circuits requiring enhanced residual current protection.
