The Siemens 5SV9316-6PK10 is a SENTRON RCBO — a combined RCD and MCB in one 1-module-wide (18 mm) package. It provides overcurrent protection (B-curve, 10 A rated) and residual current protection (30 mA, Type A) in a single device, saving DIN-rail space in final distribution boards. The 30 mA trip threshold covers personnel protection against direct contact.
The 10 A rating at 30 °C derates to 9.4 A at 40 °C and 8.4 A at 55 °C — if your panel ambient runs hot, factor that in. The B-curve (3–5 In) means it holds short-duration inrush from resistive and lighting loads but trips fast on a hard fault. Type A residual current detection handles pulsating DC fault waveforms from single-phase rectified loads (SMPS, LED drivers, appliances). The 1P+N form factor switches the line and monitors the neutral; the neutral is not switched.
Width is 18 mm (1 MW), depth 77 mm, height 90 mm. Installation depth 70 mm — ensure the enclosure has enough clearance behind the DIN rail. Rated for ambient -40 °C to 75 °C and up to 95% humidity. Silicon-free construction is noted for applications sensitive to outgassing.
