At 20 A per pole on a 400 V AC three-phase system, this breaker handles general-purpose load. IP20 with connected conductors means the busbar and wiring must be enclosed — this is a panel-mount breaker, not a standalone device. Sealable with a lead seal through the toggle slot.","metaTitle":"Siemens 5SL6420-7 SENTRON MCB, 4P C 20A 6kA","metaDescription":"Siemens 5SL6420-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 20 A, 6 kA breaking capacity per EN 60898/IEC 60947-2.
