Ratings that decide the fit
The 5SV9316-6PK32: The 30 mA residual-current trip (Type A) means it catches both sinusoidal AC faults and pulsating DC faults up to 6 mA smooth DC — the minimum required by IEC 60364 for socket-outlet circuits in most jurisdictions. The B-curve overcurrent trip (3.5 to 5 In) clears short-circuit faults fast enough for cable protection in residential and light commercial runs, but won't nuisance-trip on inrush from a few fluorescent fittings or small motors. The 6 kA SCCR at 230/400 V per EN 60898 and IEC 60947-2 is adequate for most TN and TT systems; if your service entrance has a higher prospective fault current, you'll need an upstream current-limiting MCB or fuse to back up this device. Temperature derating is built into the spec: at 40 °C ambient the continuous current drops to 30.4 A, at 50 °C to 28.8 A. In a crowded enclosure with multiple RCBOs side-by-side, expect the internal temperature to rise above ambient — factor the derated value, not the 32 A label, when sizing for continuous load. The 18 mm width (1 MW) and 77 mm depth fit standard DIN-rail enclosures; the 70 mm installation depth leaves room for wiring behind the rail.
Integration notes
Mounts on standard 35 mm DIN rail in any position. The supply feeds from below per the manufacturer's marking. IP20 rating applies only when the distribution board is installed and conductors are connected — the device itself is not sealed for wet or dusty environments. The touch-protection feature (finger-safe terminals) is built in, so no separate terminal covers are needed for the front face. Silicon-free construction matters for applications where outgassing could contaminate sensitive contacts or optics.
