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.
DS203 NC residual current circuit breakers are the ideal solution for installations where space is limited, offering many types in a width of only 4 modules, reducing the space required by 50% compared to an RCB + MCB configuration.
This makes them suitable both for new installations to save space in switchboards and for retrofitting existing installations by adding earth fault current protection in installations where this was not foreseen, without affecting the overall dimensions of the system and the placement of the whole system.
