The 10 kA breaking capacity at 400 V AC per EN 60898 tells you this breaker can safely clear a bolted fault up to 10,000 A without welding its contacts or rupturing the case. The 4 A rating limits the continuous load to about 0.96 kW per pole at 240 V or 2.76 kW total on a 400 V two-phase circuit — sized for a lighting subfeed or a small appliance group, not a main breaker. Power loss per pole is 1.2 W in hot operating state at rated current, which matters for thermal coordination inside a crowded enclosure. Halogen-free and silicon-free construction — no corrosive off-gassing under fault, which matters when the breaker shares a cabinet with sensitive electronics. Overvoltage category III (distribution-level), pollution degree 2 (non-conductive dust only).","metaTitle":"Siemens 5SL4204-7CC SENTRON MCB, 2-pole C-curve 4A 10kA","metaDescription":"Siemens 5SL4204-7CC SENTRON miniature circuit breaker, 2-pole, C-curve, 4A, 10kA breaking capacity per EN 60898 at 400V AC.
