The Siemens 5SV4448-0 is a 4-pole residual current operated circuit breaker (RCCB) from the RCCBs product family, rated at 100 A sensitivity with a 100 mA trip threshold on a 400 V AC system. Type AC detection means it responds to sinusoidal AC residual currents — the standard choice for general-purpose socket circuits and lighting feeds where no rectified or pulsed DC fault currents are expected. Note the manufacturer's caveat: use of this device is not permitted in all countries; national installation regulations must be observed.
