The Siemens 5SV4648-0 is a 4-pole residual current circuit breaker (RCCB) from the RCCBs family, rated 100 A with a 300 mA sensitivity for AC-type earth leakage detection on a 400 V AC supply. The 300 mA trip threshold suits it for general fault protection rather than supplementary personal protection (which typically calls for 30 mA). RoHS compliance is confirmed since 02-06-23, and REACH candidate-list information is available on request.
