Siemens Residual Current Protective Device

The number of electrical consumers in residential homes and commercial buildings has increased significantly in recent decades. The latest electrical devices often have quite different characteristics in terms of current consumption than earlier devices, due to frequency converters in washing machines, for example, or switched-mode power supply units in TVs, PCs or LED lights. There are also decentralized power producers like photovoltaic systems or charging devices for electric vehicles. All of this requires new protection strategies for electrical installations. This also includes appropriate residual current protection devices or residual current circuit breakers that will cut the current immediately and safely in the event of a fault.
