2CSR255163R1104 ABB DS301C C10 A30 RCBO 1P+N Type A 30mA 10A 6kA

Why Choose the ABB DS301C C10 A30 RCBO?

The ABB DS301C C10 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS301C RCBO series, it combines overcurrent and residual-current protection within a space-saving single-module device for residential, commercial, building and industrial electrical installations.

This RCBO features Type A residual-current protection, enabling detection of both sinusoidal alternating and pulsating DC residual currents. Its 30 mA rated residual operating current provides additional protection against electric shock as well as protection against earth fault currents, making it suitable for many modern circuits incorporating electronic equipment.

With a rated current of 10 A, C tripping characteristic and 6 kA rated short-circuit breaking capacity, the DS301C C10 A30 provides dependable protection for circuits that can experience moderate starting or inrush currents. Its compact 1P+N, one-module construction helps maximise available DIN-rail space in modern distribution boards.

Compact Type A Protection for Single-Phase Circuits

An RCBO combines the functions of a miniature circuit breaker and residual current device within a single protective unit. The ABB DS301C C10 A30 protects connected single-phase circuits against overload and short-circuit currents while also responding to sinusoidal alternating and pulsating DC residual earth fault currents.

The DS301C series occupies only one standard DIN-rail module, helping installers maximise usable space inside distribution boards. Its 30 mA Type A residual-current protection is well suited to modern electrical installations, while the C-curve characteristic accommodates the moderate inrush currents associated with many lighting, control and general electrical loads.

Typical Applications

• Residential electrical distribution boards.
• Commercial building final circuits.
• Lighting and control circuits.
• Circuits supplying electronic equipment capable of producing pulsating DC residual currents.
• Loads with moderate starting or inrush currents.
• Building services and industrial distribution panels.
