Why Choose the ABB DS203 A-C32/0.03 RCBO?
The ABB DS203 A-C32/0.03 is a reliable 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and earth leakage faults. As part of the ABB DS200 RCBO series, it combines residual current and overcurrent protection in a single compact protective device for commercial and industrial electrical installations.
This Type A RCBO detects sinusoidal alternating residual currents as well as pulsating DC residual currents, providing dependable protection for circuits supplying modern electrical and electronic equipment. Its integrated thermal-magnetic protection also safeguards conductors and connected equipment against overload and short-circuit conditions.
With a rated current of 32 A, a C tripping characteristic, 30 mA residual current sensitivity and 6 kA rated short-circuit capacity, the DS203 A-C32/0.03 provides coordinated protection for three-phase circuits in commercial and industrial distribution systems.

Reliable Protection for Three-Phase Circuits
RCBOs combine the functions of a miniature circuit breaker and residual current device in one unit. The ABB DS203 A-C32/0.03 therefore protects a circuit against excessive current caused by overloads or short circuits while simultaneously monitoring for potentially hazardous earth leakage currents.
Its Type A residual current characteristic makes it suitable for installations where electrical equipment may generate pulsating DC fault currents in addition to conventional sinusoidal AC residual currents. The 30 mA sensitivity provides additional protection against direct contact while supporting effective fault protection in commercial and industrial distribution systems.
Typical Applications
- Three-phase commercial electrical circuits.
- Industrial distribution boards and control panels.
- Machinery and equipment supply circuits.
- Lighting and general power distribution systems.
- Circuits requiring combined overload and earth leakage protection.
- Electrical installations requiring 30 mA Type A residual current protection.
