The 10 A rating sets the continuous load it can carry — sized for a branch circuit or a small motor load drawing under 10 A. The current-limiting action clears a fault before the prospective short-circuit current peaks, reducing let-through energy and protecting cables and busbars.
MCCBs like the S802PV-SP10 are used in distribution panels, motor control centers, and industrial switchboards to protect cables and loads against overcurrent and short circuits. The 800 V rating suits it for 690 V or 800 V industrial systems common in heavy machinery and process plants.
