This is the part you spec into a residential or light-commercial distribution board where the branch circuit needs overcurrent and short-circuit protection on a 400 V AC three-phase system. Snaps onto standard DIN rail; mounting position any. In a residential or light-commercial main distribution board with a typical upstream transformer impedance, that covers the majority of installation scenarios. The 2-pole design switches both phase and neutral — required for single-phase branch circuits where the neutral is switched. Sealable terminals (yes) allow a lockout-tagout seal across the screw terminals for isolation verification.","metaTitle":"Siemens 5SL6220-7 SENTRON MCB, 2P C-Curve 20A 6kA","metaDescription":"Siemens 5SL6220-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 20 A, 6 kA breaking capacity per EN 60898/IEC 60947-2.
