The 70 mm installation depth matches the common panel depth for SENTRON distribution boards. Lifecycle status is active per the manufacturer, so this is a current-production line item — no end-of-life watch needed for new BOM entries. ## Design and deployment context Instantaneous tripping (no short-time delay), type A detection — catches both sinusoidal AC residual currents and pulsating DC residual currents up to 6 mA, which covers most modern electronic loads like VFDs, switched-mode power supplies, and single-phase rectifiers. Silicon-free construction, important for automotive or coating-line environments where silicone outgassing can cause adhesion failures. Rated for an ambient range of -25 °C to +45 °C operating, with storage down to -40 °C. Supply voltage for testing equipment minimum 195 V; the part accepts supply from top or bottom. Mechanical service life 10,000 operating cycles typical. Supplementary devices can be installed on the product side, which gives flexibility for downstream protection coordination without a separate enclosure.","metaTitle":"Siemens 5SV3344-6 SENTRON RCCB, 4-pole, 40 A, 30 mA, 400 V A","metaDescription":"Siemens 5SV3344-6 SENTRON RCCB, 4-pole, type A, 40 A, 30 mA, 400 V AC.
