Why Choose the ABB DS201K10A30UL RCBO?
The ABB DS201K10A30UL is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and earth faults. As part of the ABB DS201 UL series, it combines residual-current and overcurrent protection in a single DIN-rail device for electrical equipment, machinery and industrial control applications.
This RCBO features a 10 A rated current, 30 mA rated residual operating current and Type K tripping characteristic. Its Type A residual-current detection responds to sinusoidal alternating and pulsating DC residual currents, providing dependable earth-fault protection alongside conventional overcurrent protection.
With a 6 kA short-circuit breaking capacity and 1P+N configuration, the DS201K10A30UL provides combined protection while helping minimise the amount of panel space required. Its K characteristic makes it particularly suitable for circuits supplying inductive loads with higher starting currents, including motors and industrial equipment.

Reliable Combined Circuit Protection
RCBOs such as the ABB DS201K10A30UL combine the functions of a miniature circuit breaker and residual-current protective device. This allows a single unit to disconnect a circuit in response to overloads, short circuits or potentially hazardous residual currents, simplifying circuit protection within electrical panels.
The K tripping characteristic is particularly useful for circuits containing inductive equipment that can draw elevated current during starting. Combined with Type A residual-current detection, the DS201K10A30UL provides versatile protection for machinery, motors and other electrical equipment.
Typical Applications
- Industrial machinery and electrical equipment.
- Motor and inductive-load circuits.
- OEM machine control panels.
- Industrial control and automation systems.
- Single-phase electrical circuits requiring combined protection.
- Electrical distribution and machine-building applications.
