2CSR254101R1137 ABB DS204 A-K13/0.03 RCBO 4P 13 A 30 mA 6 kA

Why Choose the ABB DS204 A-K13/0.03 RCBO?

The ABB DS204 A-K13/0.03 is a dependable four-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth-fault currents. As part of the ABB DS200 RCBO series, it integrates residual-current and thermal-magnetic overcurrent protection into a single DIN-rail device for efficient electrical distribution.

This RCBO has a 13 A rated current, K tripping characteristic and 30 mA rated residual operating current. Its Type A residual-current characteristic provides detection of sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for circuits supplying modern electrical and electronic equipment.

With a 6 kA rated short-circuit breaking capacity and four-pole configuration, the DS204 A-K13/0.03 is suitable for multi-pole and three-phase distribution circuits requiring coordinated residual-current and overcurrent protection. The K characteristic is particularly suited to inductive loads and equipment with higher starting currents, helping reduce unwanted magnetic tripping while maintaining effective circuit protection.

Combined Residual-Current and Overcurrent Protection

RCBOs combine residual-current protection with the overload and short-circuit protection normally provided by a miniature circuit breaker. The ABB DS204 A-K13/0.03 can therefore respond to earth-leakage faults as well as excessive circuit current, helping simplify distribution-board design by integrating these protective functions into one device.

Type A residual-current protection is suitable for circuits where electronic equipment may produce pulsating DC residual currents. Combined with its K characteristic, the DS204 A-K13/0.03 is particularly useful where inductive equipment can produce elevated starting currents while dependable residual-current and overcurrent protection remains essential.

Typical Applications

• Three-phase electrical distribution boards.
• Commercial and industrial electrical installations.
• Motor and inductive-load circuits.
• Control and automation equipment.
• Circuits supplying electronic equipment and power supplies.
• Applications requiring combined Type A residual-current and overcurrent protection.
