Why Choose the ABB DS202CR M B20 A30 50/60 RCBO?
The ABB DS202CR M B20 A30 50/60 is a compact and highly reliable two-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth fault currents. As part of the ABB DS202CR series, it combines residual current and overcurrent protection within a space-saving two-module DIN-rail device.
This RCBO provides Type A residual current protection, detecting sinusoidal alternating and pulsating direct residual currents. Its B tripping characteristic provides sensitive magnetic overcurrent protection suitable for circuits with relatively low inrush currents, while the integrated residual current function provides additional protection against direct contact at a sensitivity of 30 mA.
With a rated current of 20 A, a rated residual operating current of 30 mA and a 10 kA short-circuit breaking capacity, the DS202CR M B20 A30 50/60 provides comprehensive circuit protection in a compact format. Its 230 V AC rated operational voltage and 50/60 Hz dual-frequency compatibility make this version particularly suitable for marine electrical installations and other demanding single-phase distribution applications.

Reliable Combined Circuit and Residual Current Protection
RCBOs combine the functions of a miniature circuit breaker and residual current protection device within a single unit. The ABB DS202CR M B20 A30 50/60 therefore protects electrical circuits against excessive current caused by overloads and short circuits while simultaneously detecting residual earth leakage currents that could present a risk to people or electrical equipment.
The Type A residual current characteristic provides protection against sinusoidal alternating and pulsating direct earth fault currents. Together with its 30 mA sensitivity, B-curve overcurrent characteristic and 10 kA breaking capacity, the DS202CR provides dependable final-circuit protection while reducing the amount of space required within electrical distribution equipment.
Typical Applications
- Marine electrical distribution systems.
- Shipboard single-phase final circuits.
- Lighting and auxiliary electrical circuits.
- Socket and power distribution circuits.
- Control and equipment circuits requiring 30 mA residual current protection.
- Electrical panels requiring combined overcurrent and earth fault protection.
