This breaker is rated 16 A at both 480 V and 600 V, which tells you the thermal-magnetic trip holds that continuous current across North American line voltages. At 230 V it carries a 2 hp motor load; at 460/480 V that rises to 10 hp — so it is sized for fractional- to medium-horsepower three-phase motors. The interrupting capacity at 690 V AC is 4 kA, and the backup fuse coordination is specified: gG 63 A at 400 V, gG 50 A at 500 V, gG 40 A at 690 V. That means if a fault exceeds the breaker's own breaking capacity, the upstream gG fuse clears it before the breaker ruptures. No ground-fault or phase-failure detection is built in — those functions, if needed, must come from an external module or the downstream overload relay. ## Clearance and wiring constraints That means you can butt-mount this breaker against a panel backplate or a busbar — no breathing gap needed front or rear. The main circuit terminals are M4 screws, accepting 2x 1 to 2.5 mm² or 2x 2.5 to 10 mm² solid or stranded wire. Use a Pozidriv size 2 tip with a 5 to 6 mm shaft diameter for the terminal screws.","metaTitle":"Siemens 3RV2323-4AC10 SIRIUS Circuit Breaker, S0, 16 A at 48","metaDescription":"Siemens 3RV2323-4AC10 SIRIUS circuit breaker, size S0, 16 A at 480 V, 97x45x97 mm, screw/snap-on DIN rail mounting.
