Why Choose the ABB DS202MAC500.03 RCBO?
The ABB DS202MAC500.03 is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. Part of the proven ABB DS200 / DS202 M series, this device combines residual-current and overcurrent protection within a single DIN-rail mounted assembly for demanding commercial and industrial electrical installations.
With a rated current of 50 A, 30 mA residual-current sensitivity and Type C tripping characteristic, the DS202 M A-C50/0.03 provides dependable protection for circuits with moderate inrush currents. Its Type A residual-current detection responds to sinusoidal alternating and pulsating DC residual currents, providing broader earth leakage protection than an AC-type device.
The DS202MAC500.03 provides a rated short-circuit capacity of 10 kA and operates at 230 V AC, 50–60 Hz. ABB supplies the unit under order code 2CSR272101R1504, with a test pushbutton and indication features that support straightforward testing, inspection and fault identification.

Reliable Type A Circuit and Residual-Current Protection
RCBOs combine the functions of overcurrent and residual-current protection in a single device. The ABB DS202 M A-C50/0.03 therefore protects connected circuits against overload and short-circuit currents while also detecting sinusoidal alternating and pulsating DC residual currents that can occur in modern electrical equipment.
The ABB DS200 range is designed for demanding commercial and industrial applications. Its factory-combined construction simplifies assembly and wiring, while the integrated test pushbutton, earth fault indication and contact-position indication support efficient testing, maintenance and fault identification.
Typical Applications
- Commercial electrical distribution boards.
- Industrial electrical installations.
- Higher-current final circuit protection.
- Lighting and general power circuits.
- Electrical equipment incorporating electronic components.
- Electrical control and distribution panels.
- Circuits requiring combined 30 mA Type A residual-current and overcurrent protection.
