The 4.5 kA breaking capacity at 400 V AC is the standard rating for this class under both the domestic (EN 60898) and industrial (IEC 60947-2) standards, covering most panelboard fault scenarios. Rated current is 63 A at 30 °C, derating to 59.18 A at 40 °C and 52.93 A at 55 °C — account for the thermal derating when populating a densely packed enclosure. The 10 000 mechanical switching cycles typical service life reflects a residential/infrastructure duty profile rather than a high-cycling industrial process. Mounting position is unrestricted, and the IP20 protection class (with connected conductors) is standard for enclosed panelboard use. The sealable design allows lockout-tagout application without removing the breaker. The halogen-free and silicon-free construction avoids corrosive off-gassing in enclosed spaces — relevant for marine and HVAC applications where sensitive electronics share the enclosure. The 5SL3363-6 carries the SENTRON brand designation and is classified per IEC 81346-2 and DIN EN 61346-2 as function F (protective device). Energy limitation class 3 indicates moderate let-through energy, appropriate for downstream branch circuit protection. No official successor or replacement has been announced. The 5SL3363-6 remains the active order code for a 3-pole, B-curve, 63 A MCB in the SENTRON 5SL6 series. If a panel was specified around a different SENTRON variant (e.g., a C-curve or lower ampacity), verify the tripping characteristic and thermal derating before substitution — the mechanical footprint and DIN-rail mounting are shared across the family.","metaTitle":"Siemens 5SL3363-6 SENTRON MCB, 3-pole B-curve 63 A, 4.5 kA","metaDescription":"Siemens SENTRON 5SL3363-6 miniature circuit breaker, 3-pole, B characteristic, 63 A rated at 400 V AC, 4.5 kA breaking capacity per EN 60898.
