## Summary description

The ABB DS203NC is a high-performance RCBO designed to provide both residual current and overcurrent protection in electrical circuits. Featuring a 13A rated current, Type A sensitivity, and B-trip curve, this 3P+N device ensures reliable safety for industrial and residential installations. It operates at 50/60 Hz with a total power loss of 7.2 W, offering efficient protection against short circuits and earth leakage faults.

## Long description

The ABB DS203NC is a high-performance residual-current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in both residential and industrial environments. This 3P+N device integrates protection against short-circuit currents, overloads, and earth fault currents into a single compact unit, ensuring reliable operation and enhanced safety for electrical installations.
Advantages
This RCBO offers a robust solution for modern electrical systems by combining multiple protective functions into a space-saving design. Its Type A sensitivity ensures detection of both AC and pulsating DC residual currents, providing a higher level of safety compared to standard devices. The B-trip curve is specifically calibrated for applications where low-level short-circuit protection is required, making it an efficient choice for protecting sensitive equipment and general wiring circuits.
Suitable for
Residential electrical distribution boards
Industrial machinery and control panels
Protection against indirect contact
Additional protection against direct contact
Circuits requiring combined overload and earth leakage protection
This device may not be suitable for applications requiring a C or D trip curve, such as circuits with high inrush currents from large motors or transformers. It is also not intended for use in environments exceeding its specified IP2X protection rating without additional enclosure protection.
Key specifications
Rated current: 13 A
Trip curve: B-Curve
Sensitivity type: Type A
Poles: 3P+N (4 poles)
Breaking capacity: 6000 A
Frequency: 50/60 Hz
Power loss: 7.2 W
Dimensions: 85 mm x 71 mm x 69 mm
Protection rating: IP2X
The device should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted on a standard DIN rail within a distribution board. Ensure that the supply voltage and load requirements are compatible with the 13A rating before installation. Once mounted, the device can be manually operated using the front toggle switch to reset or disconnect the circuit.
What to consider before purchase
Verify the required trip curve (B-curve) for your specific load type
Ensure the 13A rated current matches your circuit requirements
Check available space in your distribution board for the 4-module width
Confirm that the Type A sensitivity meets your safety standards
Usage recommendations: Regularly test the residual current functionality using the integrated test button to ensure the device remains in optimal working condition.
