The 4-pole design with neutral switching (3P+N) covers three-phase plus neutral circuits common in European-style panels, and the 4-module width (72 mm) occupies standard 18 mm-per-module DIN-rail spacing. ## Temperature derating and ambient limits At 40 °C it derates to 47.36 A, at 45 °C to 46 A, and at 55 °C to 43.09 A. ## Physical fit and installation Dimensions: 72 mm wide (4 modular units), 90 mm high, 76 mm deep. Installation depth is 70 mm, leaving clearance behind the DIN rail for wiring. Sealable terminals and touch protection are built in, which matters for installations requiring a lockable cover or tamper-evident seal. ## Environmental and material compliance The energy limitation class is 3, meaning it limits let-through energy under fault conditions to reduce stress on downstream equipment.","metaTitle":"Siemens SENTRON 5SL4650-8 MCB, 4P, D-curve, 50 A, 10 kA","metaDescription":"Siemens SENTRON 5SL4650-8 miniature circuit breaker, 4-pole (3P+N), D tripping characteristic, 50 A rated at 30 °C, 10 kA breaking capacity per EN 60898 and IEC 60947-2.
