The 100 mA sensitivity means it's sized for equipment protection or fire-prevention circuits rather than personal shock protection (which typically calls for 30 mA or lower). Supply can land top or bottom — no forced orientation. IP20 with conductors connected and the distribution board installed; that's standard for enclosed panel gear, not for open washdown areas. Ambient range -25 °C to +45 °C operating, with storage extremes of -40 °C to +75 °C. The 4-pole form factor handles three-phase plus neutral in one unit — no separate neutral bar needed downstream. ## Fault handling and endurance Rated conditional short-circuit current per IEC 61008-1 is 0.5 kA in series with a backup fuse; the 6 kA SCCR applies when the device clears the fault alone. Let-through current is limited to 5 200 A, and the permissible I²t value is 58 000 A²·s — useful figures for checking selectivity with downstream MCBs. Mechanical life is 2 000 switching cycles, which is typical for an RCCB that sees infrequent manual test operations rather than daily load switching. Overvoltage category III, so it's rated for fixed-installation distribution boards, not for plug-in portable gear.","metaTitle":"Siemens SENTRON 5SV5444-0 RCCB, 4P, 40A, 100mA, Type AC","metaDescription":"Siemens SENTRON 5SV5444-0 4-pole RCCB, 40 A rated, 100 mA trip, Type AC, 6 kA SCCR.
