The B-curve means it trips magnetically at 3–5× rated current — fast enough for short-circuit protection of resistive and small inductive loads, but without the nuisance tripping that a C-curve could cause on inrush. That 13 A at 30 °C is the headline number, but if your enclosure runs at 40 °C the effective rating drops to 12.37 A; at 55 °C it's 11.36 A. Plan your load margin accordingly. ## Sizing and derating — the temp curve matters The 5SL6313-6 carries a full derating table: 13 A at 30 °C, 12.37 A at 40 °C, 11.96 A at 45 °C, 11.36 A at 55 °C. If your panel is in a hot mechanical room or a nacelle that sees 55 °C ambient, you lose about 1.6 A off the headline rating. That's a real margin call — size the upstream protection and downstream load with the hot rating, not the 30 °C sticker. ## DIN-rail fit and enclosure integration Mounts in any position — vertical, horizontal, flat — which helps when you're packing a tight sub-panel. Sealable and touch-protected per the product feature list. ## Where this MCB belongs — residential and infrastructure Suitability for operation is listed as residential buildings and infrastructure. That matches the B-curve and 6 kA rating — typical for final distribution in apartment blocks, lighting panels, HVAC sub-panels, and light commercial. Not a motor-protection breaker (no thermal-magnetic curve tuned for motor inrush), but fine for general branch-circuit protection.","metaTitle":"Siemens 5SL6313-6 SENTRON MCB, 3P B-Curve 13A 6kA","metaDescription":"Siemens 5SL6313-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 13 A at 30 °C, 6 kA breaking capacity per IEC 60898.

The 5SL6313-6 is a B-curve 13 A device; the 5SL6016-7KL is a different rating and curve. Mechanically they share the same footprint, so no rewiring needed for the panel — but verify the electrical ratings match your circuit."},{"question":"What compliance documentation does Siemens provide for the 5SL6313-6?","answer":"The product carries IEC 60898 and IEC 60947-2 ratings, overvoltage category III, pollution degree 2, and is halogen-free and silicon-free.
