Why Choose the ABB DS203NCB16AC100 RCBO?
The ABB DS203NCB16AC100 is a compact and reliable 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect three-phase electrical circuits against overloads, short circuits and earth fault currents. As part of the ABB DS203NC range, it combines residual current and overcurrent protection in a space-saving device for commercial and industrial electrical distribution systems.
With a 16 A rated current, B tripping characteristic and 100 mA residual current sensitivity, the DS203NC B16 AC100 provides coordinated protection against overcurrent and sinusoidal alternating residual currents. Its Type AC residual current detection makes it suitable for circuits where sinusoidal AC earth leakage currents are expected.
The DS203NCB16AC100 provides a 6 kA rated short-circuit breaking capacity (Icn) and is designed for 3P+N circuits. Its compact DIN-rail construction combines multiple protection functions in a single unit, helping simplify distribution-board design and make efficient use of available installation space.
