The 3P+N pole arrangement gives you three protected phases plus a switched neutral, which is the standard for single-phase or three-phase distribution in a panel where you want neutral isolation. Terminals accept solid or stranded copper from 0.75 to 25 mm², with a tightening torque of 2.5 to 3 N·m. That covers most panel-building wire sizes up to 4 AWG. ## Deployment context Snap-on DIN-rail mounting (: any position) and IP20 protection with connected conductors make this a standard panel-mount MCB for distribution boards in residential buildings and infrastructure. The -25 to +45 °C ambient range covers most indoor electrical rooms; derate above that per the thermal curve. The sealable design lets the installer lock the toggle position to prevent unauthorized reset — useful for safety circuits or critical loads.","metaTitle":"Siemens 5SL3650-6 SENTRON MCB, 50 A, 4.5 kA, B Curve, 3P+N","metaDescription":"Siemens 5SL3650-6 SENTRON miniature circuit breaker, 50 A rated, B tripping characteristic, 4.5 kA breaking capacity per EN 60898, 3P+N, 400 V AC.
