It breaks fault currents up to 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235. ## B-curve trip and thermal derating The 3 A rating holds at 35 °C ambient; at 40 °C it derates to 2.76 A, at 50 °C to 2.49 A, and at 55 °C to 2.34 A. If the panel runs hot (enclosed DIN rail, poor airflow), size up one step or account for the derated figure in the load calculation. Occupies 1 modular unit (18 mm width) on standard DIN rail. The quick-assembly fastening system snaps onto the rail without tools; mounting position is any. Sealable terminals (top and bottom combined) let the panel builder lock the cover after commissioning — useful for utility-metering or tamper-evident enclosures. Listed as current production (active lifecycle stage). Halogen-free and silicon-free construction, which matters for clean-room or semiconductor-adjacent panels where outgassing contaminates optics or contacts.","metaTitle":"Siemens 5SY6103-6CC SENTRON MCB, 1P B-Char 3A, 6kA","metaDescription":"Siemens 5SY6103-6CC SENTRON miniature circuit breaker, 1-pole B-curve, 3 A rated, 6 kA breaking capacity per EN 60898.

The electrical difference is the rating: 5SY6103-6CC is 3 A B-curve; 5SY4116-6CC is 16 A B-curve.
