2CSR253001R1064 ABB DS203 AC-C6/0.03 RCBO 3P Type AC 6A 30mA 6kA

Why Choose the ABB DS203 AC-C6/0.03 RCBO?

The ABB DS203 AC-C6/0.03 is a three-pole Type AC 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 / DSH200 RCBO range, it integrates residual-current and overcurrent protection in a single DIN-rail device for three-phase commercial and industrial electrical distribution systems.

With a rated current of 6 A, a rated residual operating current of 30 mA and a 6 kA rated short-circuit breaking capacity, the DS203 AC-C6/0.03 provides coordinated protection for lower-current three-phase circuits. Its Type AC residual-current characteristic is designed to detect sinusoidal alternating residual currents, while its three-pole construction provides protection across all three phases.

The C tripping characteristic makes this RCBO suitable for circuits where moderate temporary inrush currents can occur during normal operation. Combining a 6 A current rating, 30 mA residual-current sensitivity and three-pole configuration, the DS203 AC-C6/0.03 is well suited to three-phase control, distribution and equipment circuits requiring compact combined protection.

Reliable Three-Phase Circuit Protection

An RCBO combines the protective functions of an overcurrent circuit breaker and a residual current device in a single assembly. The ABB DS203 AC-C6/0.03 therefore protects connected three-phase circuits against overload and short-circuit currents while monitoring for sinusoidal AC residual earth fault currents.

The C characteristic is suitable for circuits that can experience moderate temporary inrush currents without requiring a higher-inrush tripping characteristic. Together with its three-pole construction and 30 mA Type AC residual-current protection, this makes the DS203 AC-C6/0.03 a practical solution for suitable three-phase control, distribution and equipment circuits.

• Three-phase commercial electrical distribution systems.
• Industrial electrical distribution boards.
• Three-phase control and auxiliary circuits.
• Industrial control panels and switchboards.
• Circuits with moderate equipment inrush currents.
