The broad range of capability of 3 kA. tripping characteristic of RCCBs type F lies Residual current protective devices type F 7. Higher load rating with smooth between type A and type B, which ensures includes RCCBs, RC units and RCBOs DC Residual currents up to 10 mA. reliable coverage of the type of fault current forms that can arise when using single- phase loads with frequency converters. Answers for infrastructure. Siemens AG 2012. Residual current protective devices Residual current protective devices , type F. Application Residual current protective devices type F not only offer the full Increased current withstand capability of > 3 kA (8/20 s). range of protection and function features provided by type A, The tripping characteristics are not influenced by DC Residual they are also ideal for the detection of Residual currents with currents up to 10 mA.
