Panel-builder commissioning note
The SENTRON 5SQ2360-0KA06 is a 3-pole miniature circuit breaker with B-curve tripping characteristic, rated 6 A at 400 V AC, 50 Hz. Degree of pollution 3 and overvoltage category 3 suit it for fixed installations inside a panel.
B-curve selectivity and load fit
The 6 A rating on a 400 V three-phase circuit handles about 4.1 kW of resistive load. For comparison, the sibling 5SQ2370-2YA04 shares the same 3-pole, 3 kA, 400 V frame but uses C-curve (5–10× In) and a 4 A rating — better for moderate inductive loads like small pumps. If your BOM calls for motor protection, the C-curve sibling is the closer fit; if it's general lighting or heater circuits, this B-curve unit is the right call.
