Single-phase line-to-neutral service tops out at 253 V AC. The 72 V DC maximum makes it usable for some DC branch circuits, but the C-curve magnetic trip is optimised for AC inrush — verify DC coordination if that is the application. ## Panel footprint and environment Overall dimensions 76 mm deep × 54 mm wide × 90 mm tall.","metaTitle":"Siemens 5SL1380-7MB SENTRON MCB, 80A 3P C-Curve, 3kA","metaDescription":"Siemens 5SL1380-7MB SENTRON miniature circuit breaker, 80 A, 3-pole, C characteristic, 3 kA per IEC 60947-2. 440 V AC, 50/60 Hz.
