2CSR275080R3064 ABB DS201MC6AC300 RCBO 1P+N C6 Type AC 300 mA

Why Choose the ABB DS201MC6AC300 RCBO?

The ABB DS201MC6AC300 is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and residual earth fault currents. With ABB order code 2CSR275080R3064, this device forms part of the established ABB DS200 / DS201 M RCBO range for residential, commercial and industrial electrical distribution applications.

Combining miniature circuit breaker and residual current protection within a single two-module device, the DS201 M C6 AC300 provides coordinated circuit protection while reducing the need for separate protective components. Its Type AC residual current detection responds to sinusoidal alternating residual currents, while the C tripping characteristic is suitable for circuits and equipment with moderate inrush currents.

With a rated current of 6 A, a 300 mA rated residual operating current and a 230–240 V AC rated operational voltage, the DS201MC6AC300 provides combined overcurrent and earth leakage protection for suitable single-phase circuits. Its 10 kA rated short-circuit breaking capacity and compact 1P+N construction make it a robust solution for modular electrical distribution systems.

Reliable Combined Circuit Protection

RCBOs such as the ABB DS201MC6AC300 combine overcurrent and residual current protection within one modular device. The overcurrent section responds to overload and short-circuit conditions, while the residual current function detects sinusoidal alternating leakage currents to earth and disconnects the circuit when the specified threshold is reached.

The DS201 M range is designed for end-user single-phase circuits requiring dependable protection within a compact footprint. The DS201MC6AC300 combines a 6 A C-curve overcurrent characteristic with 300 mA Type AC residual current sensitivity, providing a practical solution for appropriately designed residential, commercial and industrial electrical circuits.

Typical Applications

• Single-phase electrical distribution boards.
• Commercial electrical circuits.
• Industrial electrical distribution systems.
• Lower-current lighting and electrical circuits.
• Control panels and auxiliary electrical circuits.
• Building electrical distribution systems.
• Single-phase equipment circuits requiring combined overcurrent and earth leakage protection.
