The 4-pole type A design detects both sinusoidal AC residual currents and pulsating DC residuals up to 30 mA — the threshold for personal protection against electric shock. At 63 A continuous rating it covers most sub-distribution, lighting, and general-power circuits in commercial and industrial panels. Mounts on DIN rail (REG) in any position; the 72 mm width (4 modular units at 60 mm grid spacing) fits four pole spaces. Installation depth is 70 mm. IP20 rating applies only when the distribution board is installed with connected conductors — this is an enclosed-panel device, not a standalone weatherproof unit. The silicon-free construction suits environments where silicone outgassing can contaminate contacts or optics. Rated for 50 Hz only (not 50/60 Hz), so confirm supply frequency before specifying.
The 5SV3346-6 is an active, current-production part in the SENTRON family.
