2CSR255180R3064 ABB DS201 C6 A300 RCBO 1P+N 6A Type A 300mA 6kA

Why Choose the ABB DS201 C6 A300 RCBO?

The ABB DS201 C6 A300 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS200 / DS201 RCBO range, it combines residual current and overcurrent protection in one modular protective device for residential, commercial and industrial electrical distribution.

This RCBO provides a 6 A rated current, C tripping characteristic and 300 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, while the C characteristic is suited to general-purpose circuits and equipment with moderate inrush currents.

With a 1P+N configuration and 6 kA rated short-circuit breaking capacity, the DS201 C6 A300 provides combined circuit and residual current protection in a compact DIN-rail format. ABB order code 2CSR255180R3064 identifies this specific 6 A, C-curve, Type A, 300 mA version.

Combined Residual Current and Overcurrent Protection

RCBOs such as the ABB DS201 combine the functions of a miniature circuit breaker and a residual current protective device. The DS201 C6 A300 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when residual current reaches the device's operating threshold.

The Type A characteristic enables detection of sinusoidal alternating and pulsating direct residual currents. Combined with its 300 mA sensitivity, C tripping characteristic and compact 1P+N construction, the DS201 C6 A300 provides coordinated protection for suitable electrical distribution, control and auxiliary circuits.

Typical Applications

• Single-phase electrical distribution circuits.
• Commercial and industrial electrical installations.
• Control and auxiliary circuits.
• Automation and machinery control circuits.
• Circuits supplying equipment with moderate inrush currents.
• Electrical distribution boards and control panels.
