It's not for high-inrush transformer primaries (that wants a K or D curve) or for sensitive electronics (that wants a B curve). The 100 A rating on a single pole at 400 V AC means it's typically used as a branch-circuit protector in a three-phase panel where each phase gets its own 1-pole breaker, or as a single-phase main. ## DIN-rail fit and panel integration Width is 27 mm (1.5 MW), depth 76 mm, height 90 mm, with an installation depth of 70 mm into the panel. The tunnel terminals top and bottom accept standard copper conductors. Sealable design means the toggle can be locked in the off position for lockout/tagout compliance.","metaTitle":"Siemens 5SP4191-7 SENTRON MCB, 1P C 100A 10kA","metaDescription":"Siemens 5SP4191-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 100 A, 10 kA per EN 60898, 400 V AC.
