The 5SL6306-7MB occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm — the same footprint as the 3-pole 5SL4363-7 and the 5SY6332-7CC, so it drops into the same panel cut-out without re-drilling. ## Electrical ratings and application Rated for AC operation at 400 V (multi-phase) and 250 V (single-phase), with a maximum of 440 V. The DC rating tops out at 72 V — useful for control-circuit protection in a panel that also carries a DC bus. Mechanical life is 10,000 operating cycles typical, and the power loss per pole at rated current in hot state is 0.86 W, so three poles dissipate about 2.6 W total — negligible for thermal budgeting in a standard enclosure.","metaTitle":"Siemens 5SL6306-7MB SENTRON MCB, 3P C 6A 6kA 400V","metaDescription":"Siemens 5SL6306-7MB SENTRON miniature circuit breaker, 3-pole, C-curve, 6 A, 6 kA breaking capacity per EN 60898 at 400 V AC.
