That makes it suitable for circuits without rectified loads, VFDs, or UPS systems where DC leakage is present. For mixed loads, a Type A or Type B RCCB would be needed. The 25 A rating and 400 V AC supply voltage (230/400 V range) suit it for three-phase sub-distribution or feeder circuits in commercial or light industrial panels. The short-circuit current rating (SCCR) is 10 kA per IEC 61008-1, with a maximum permissible series fuse of 80 A. In a panel, coordinate the upstream breaker to ensure the SCCR of the assembly is met. Rated for overvoltage category III, it is designed for fixed installation in the distribution board, not for plug-in or portable use. Snap-on DIN rail (REG) mounting, any position. Depth is 70 mm, matching the standard installation depth for SENTRON modular devices. The 72 mm width (4 MW) means it occupies four 18 mm slots on the rail. Supply can be connected from top or bottom. Supplementary devices (like auxiliary switches or shunt trips) can be installed on the side — check the product extension options for compatibility.","metaTitle":"Siemens 5SV4442-0 SENTRON RCCB, 4P, 25A, 100mA, 400V AC","metaDescription":"Siemens SENTRON 5SV4442-0 RCCB, 4-pole Type AC, 25 A, 100 mA, 400 V AC.
