带过电流保护的剩余电流动作断路器（rcbo）主要适用于同时需要过电流保护（过载和短路）与接地故障电流保护功能的应用。 可以检测故障并及时脱扣，保障工作人员及设备安全。

In addition to the existing DS201 (2019) RCBO series (2 modules width), ABB is introducing this new generation of RCBO called DS301C (1 module width) for space-related applications. This new product is the perfect combination of MCB Unibis and ABB RCCB technologies.

RCBO DS201 Data sheet The 1P+N DS201 RCBOs are the perfect solution for a complete protection against overcurrent and earth fault currents. In two modules width the series ensure, at any time and under any condition, the safety of people, facilities and related equipment. DS201 is a 1P+N RCBO compliant to product

Why use an RCBO rather than combining an MCB and an RCCB? — Why use the DS301C rather than the DS201? — What are the reference standards? The difference lies in the fact that in the event of a problem arising from faulty insulation, having an RCBO allocated to each individual circuit means that just the circuit with a fault can be dis-

The residual current operated circuit breakers with integral overcurrent protection (RCBO) DS261/DS271 are a combination of an MCB and an RCCB in one unit in a compact housing (1 module). RCBO´s are used to provide supplimentary protection for people from the risk of electrocution and pro-

DS201 RCBOs offer protection of end user single-phase circuits against overload and short-circuit currents, protection against the effects of sinusoidal alternating and direct pulsating earth fault currents as well as protection against indirect contact …

The DS301C RCBO is the best solution for preventing leakage currents in a variety of applications, including residential houses and flats, commercial shops, and industrial railways. — Benefits The DS301C RCBO series is the perfect slim solution against overcurrent and earth fault currents, thanks to its main benefits. Improved efficiency for ...

ds203nc 3p+n rcbo Minimum space, maximum protection The DS203NC range of 3P+N residual current circuit breakers with overcurrent protection has been designed to meet the requirements of protection devices that suit the different types of circuits of modern three-phase systems, which are increasingly compact and sensitive.

ABB’s System pro M compact® line of modular products. With the same width as standard MCBs, the RCBOs are fully integrated with ABB’s range of Consumer Units and Distribution Boards. Suitable to work from -25 °C to +55 °C ambient temperatures, the DSE201 RCBOs cover all applications offering, in only one
