Why Choose the ABB DS301CT B16 A30 RCBO?
The ABB DS301CT B16 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) developed for traction applications and designed to protect single-phase circuits against overloads, short circuits and earth leakage faults. Combining overcurrent and residual current protection within one device provides dedicated circuit protection in a space-efficient modular format.
This RCBO has a rated current of 16 A, a B-curve tripping characteristic and a rated residual operating current of 30 mA. Its Type A residual current characteristic responds to sinusoidal AC and pulsating DC residual currents, while its 6 kA breaking capacity provides dependable short-circuit protection for appropriately designed circuits.
The DS301CT range is specifically intended for traction applications and meets the R22, R23 and R26/HL3 hazard-level requirements of EN 45545-2. The DS301CT B16 A30 combines these traction-focused characteristics with compact 1P+N construction and a weight of approximately 0.1 kg, making it suitable for demanding electrical distribution environments where installation space is important.

Type A Protection for Traction Applications
The ABB DS301CT B16 A30 combines residual current protection with overload and short-circuit protection within a single RCBO. Its Type A residual current characteristic provides protection against the effects of sinusoidal alternating and direct pulsating earth fault currents. With a rated residual current of 30 mA, it also provides additional protection against direct contact when correctly selected and installed.
The B-curve characteristic is suitable for appropriate circuits with relatively low normal starting or inrush currents, while its 16 A rating and 6 kA breaking capacity provide coordinated overcurrent protection. The DS301CT series is specifically designed for traction environments and meets relevant EN 45545-2 fire behaviour requirements for R22, R23 and R26 at hazard level HL3.
Typical Applications
- Traction electrical distribution systems.
- Railway and rolling-stock electrical applications.
