The 70 mm installation depth matches standard SENTRON enclosure back-panel clearance. Mounting position is unrestricted — vertical or horizontal panel orientation works. Type AC detection means it trips on sinusoidal AC residual currents only — suitable for circuits with resistive, inductive, or simple electronic loads where no pulsed DC or frequency-converter leakage is present. The 100 mA sensitivity is a high-threshold device, typically used for fire protection or equipment-level isolation rather than personnel shock protection (which requires ≤30 mA). Rated 230/400 V AC, so it handles both single-phase (L-N, 230 V) and three-phase (L-L, 400 V) circuits. Supply connection can be top or bottom — no mandatory orientation for line/load. IP20 with conductors connected — the enclosure must be closed during operation; this is standard for panel-mounted distribution gear, not for wet or outdoor locations without a higher-rated outer cabinet.","metaTitle":"Siemens 5SV4444-0 SENTRON RCCB, 4P, 40A, 100mA, 400V AC","metaDescription":"Siemens 5SV4444-0 SENTRON RCCB, 4-pole Type AC, 40 A, 100 mA residual, 230/400 V AC, 10 kA SCCR.
