New residual current breakers with overload save 50 percent space in electric distribution boards

New residual current breaker (RCBO) 5SV1

​The 5SV1 RCBOs expand the residual current protective devices out of the Sentron portfolio from Siemens. All components are available in several types and versions. They each detect different types of residual current and are suitable for different areas of application. The 5SV1 RCBOs are available as Type AC and Type A. These versions trip in the event of sinusoidal AC residual currents, which can occur on almost all electrical loads. Type A RCBOs also detect pulsating DC residual currents. These can occur, for example, in residential and non-residential buildings having single-phase loads with electronic components in the power supply, e.g. in the case of electronic voltage reducers or dimmers.
