Why Choose the ABB DS204MAB160.03 RCBO?
The ABB DS204MAB160.03, manufacturer type DS204 M A-B16/0.03, is a four-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the ABB DS200 M series, it combines overcurrent and residual current protection within a single DIN-rail device for dependable electrical distribution.
This RCBO has a 16 A rated current, B tripping characteristic and 10 kA rated short-circuit breaking capacity. Its Type A residual current protection detects sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for modern electrical circuits containing equipment with electronic components.
With a rated residual operating current of 30 mA and a 230/400 V AC rated voltage, the DS204 M A-B16/0.03 provides additional protection against electric shock while protecting wiring and connected equipment against overcurrent conditions. Its four-pole configuration, compact modular construction and DIN-rail mounting make it well suited to residential, commercial and industrial distribution boards.

Reliable Combined Circuit and Residual Current Protection
An RCBO combines the protective functions of a miniature circuit breaker and a residual current device. The ABB DS204 M A-B16/0.03 therefore protects connected wiring and equipment against overload and short-circuit currents while continuously monitoring the circuit for potentially hazardous leakage current to earth.
Its Type A residual current characteristic enables detection of sinusoidal AC and pulsating DC residual currents. Together with 30 mA sensitivity, B-curve overcurrent response and a 10 kA breaking capacity, the DS204MAB160.03 provides comprehensive circuit protection in a compact four-pole format.
Typical Applications
- Residential and commercial electrical distribution boards.
- Three-phase electrical distribution circuits.
- Industrial switchboards and control panels.
- Lighting and general-purpose circuits.
- Circuits supplying equipment with electronic components.
- Installations requiring combined overload, short-circuit and residual current protection.
