2CSR255180R2104 ABB DS201 C10 A100 RCBO 1P+N 10A Type A 100mA 6kA

Why Choose the ABB DS201 C10 A100 RCBO?

The ABB DS201 C10 A100 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and earth leakage faults. As part of the ABB DS200 / DS201 RCBO range, it combines residual current and overcurrent protection in a single modular device for efficient electrical distribution and final-circuit protection.

This RCBO provides a 10 A rated current, C tripping characteristic and 100 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, while the C characteristic is suitable for general-purpose circuits and equipment with moderate inrush currents.

With a 1P+N configuration and 6 kA rated short-circuit breaking capacity, the DS201 C10 A100 provides combined circuit and earth fault protection in a compact DIN-rail format. ABB order code 2CSR255180R2104 identifies this specific 10 A, C-curve, Type A, 100 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 C10 A100 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when residual current to earth reaches the device's operating threshold.

The Type A residual current characteristic provides detection of sinusoidal alternating and pulsating direct residual currents. Combined with its 100 mA sensitivity, C tripping characteristic and compact 1P+N construction, the DS201 C10 A100 provides practical protection for suitable residential, commercial and industrial electrical circuits.

Typical Applications

• Single-phase electrical distribution circuits.
• Commercial electrical installations.
• Lighting and building-services circuits.
• Control and auxiliary circuits.
• Circuits supplying equipment with moderate inrush currents.
• Industrial control panels and distribution boards.
