Why Choose the ABB DS201TB10A30 RCBO?
The ABB DS201TB10A30, type designation DS201T B10 A30, is a compact 1P+N 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 DS201T traction RCBO series, it combines overcurrent and residual-current protection in a single device for railway, rolling stock and traction applications.
This RCBO features a 10 A rated current, B tripping characteristic and Type A residual-current protection. Its rated residual operating current of 30 mA provides additional protection against electric shock, while Type A detection responds to sinusoidal alternating and pulsating DC residual currents.
With a rated short-circuit breaking capacity of 6 kA and a 1P+N configuration, the DS201T B10 A30 provides coordinated circuit and residual-current protection in a compact DIN-rail device. ABB order code 2CSR255188R1105 identifies this specific 10 A, B-curve, 30 mA Type A variant.

Reliable Circuit Protection for Railway Applications
RCBOs combine the functions of a miniature circuit breaker and residual-current device, allowing one protective device to respond to overloads, short circuits and potentially hazardous earth leakage currents. This helps provide comprehensive protection while reducing the number of separate protective devices required in an electrical installation.
The ABB DS201T range is intended for railway, rolling stock and traction installations. The DS201T B10 A30 provides B-curve overcurrent protection together with 30 mA Type A residual-current protection, making it suitable for single-phase circuits requiring dependable combined protection.
Typical Applications
- Railway electrical installations.
- Rolling stock electrical systems.
- Traction applications.
- Single-phase auxiliary circuits.
- Electrical distribution and control circuits.
- Circuits requiring combined overload, short-circuit and earth leakage protection.
