2CSR252101R1167 ABB DS202 A-K16/0.03 RCBO 2P Type A 16A 30mA 6kA

Why Choose the ABB DS202 A-K16/0.03 RCBO?

The ABB DS202 A-K16/0.03 is a two-pole Type A residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth fault currents. Part of the ABB DS200 / DSH200 RCBO range, it combines residual-current and overcurrent protection within a single DIN-rail device for commercial and industrial electrical distribution systems.

With a rated current of 16 A, a rated residual operating current of 30 mA and a 6 kA rated short-circuit breaking capacity, the DS202 A-K16/0.03 provides comprehensive circuit and personnel protection. Its Type A residual-current characteristic detects sinusoidal AC residual currents as well as pulsating DC residual currents, making it suitable for circuits supplying a wide variety of modern electrical equipment.

The K tripping characteristic is particularly suited to circuits containing motors, transformers and auxiliary equipment where temporary current peaks can occur during start-up. The DS202 A-K16/0.03 is designed to tolerate high starting-current peaks while retaining sensitive thermal protection against sustained overcurrents, helping reduce unwanted tripping in demanding commercial and industrial applications.

Reliable Combined Circuit and Residual-Current Protection

An RCBO combines the functions of a miniature circuit breaker and residual current device in a single protective component. The ABB DS202 A-K16/0.03 therefore protects the connected circuit against overload and short-circuit currents while also monitoring for potentially dangerous residual earth fault currents.

Its K characteristic makes this model particularly useful where equipment can draw significant temporary starting currents. Applications involving motors, transformers and auxiliary circuits can generate current peaks during normal operation, and the K characteristic is designed to accommodate these conditions while continuing to provide effective protection for cables, circuits and connected equipment.

Typical Applications

• Industrial motor circuits and machinery.
• Transformer and auxiliary circuits.
• Commercial electrical distribution systems.
• Industrial control panels and switchboards.
• Circuits with elevated equipment starting currents.
• DIN-rail distribution boards requiring combined RCBO protection.
