The Siemens SENTRON 5SL6310-7 is a 3-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 10 A and a 6 kA breaking capacity at 400 V AC. For a 3-pole device on a 400 V three-phase supply, that covers the vast majority of commercial and light industrial panelboards. The 10 A rating at the hot operating state dissipates 1.3 W per pole — useful to know for thermal budgeting inside a crowded enclosure.
Panel integration and mounting notes
Snap-on mounting for DIN rail (EN 60715). Mounting position is any, so vertical or horizontal rail orientation is fine.
Siemens designates this for residential buildings and infrastructure — think apartment distribution boards, small commercial panels, lighting circuits, and general-purpose socket outlets. The 10 A C-curve is a common choice for lighting final circuits and small appliance loads in European-style panelboards.
