Siemens 5SV43460RC Specifications, Features & Compatibility Guide

The 30mA sensitivity is essential for residential life safety because it interrupts power before leakage currents reach levels that cause cardiac arrest. While the 63A rated current handles the full load of a large flat, the 10kA conditional short circuit rating ensures the unit remains intact during fault conditions when paired with a coordinated MCB. Utilizing 4 poles allows for complete isolation of both three phases and the neutral, which is vital for preventing neutral-to-earth faults.
