Its 6 kA breaking capacity per EN 60898 (and matching 6 kA per IEC 60947-2) suits it for final subcircuit protection in commercial and light industrial panels — think lighting, socket outlets, and small motor loads where the fault current at the board stays under that threshold. The 5SJ6 design carries a 70 mm installation depth and occupies 3 modular width units on the DIN rail. The 16 A rating at 400 V AC three-phase covers a 3-pole load; the same breaker also carries a DC rating of 60 V maximum, so it can serve a 60 V DC control bus if needed. Breaking capacity of 6 kA per both EN 60898 and IEC 60947-2 means it will safely interrupt a fault up to that level without welding its contacts. The 440 V insulation voltage and overvoltage category 3 confirm it is built for fixed-installation mains distribution. ## Deployment context — panel integration and environment For environmental tolerance: storage range from -40 °C to +75 °C, periodic ambient up to +55 °C at 95 % humidity. Halogen-free and silicon-free construction matters in clean-room or corrosive-plant environments where outgassing can foul contacts or optics.","metaTitle":"Siemens 5SJ6316-7 SENTRON MCB, 3-Pole C 16A 6kA","metaDescription":"Siemens 5SJ6316-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 16 A, 400 V AC, 6 kA breaking capacity per EN 60898.
