Occupies 3 modular width units (54 mm) on a DIN rail, with a 76 mm depth and 70 mm installation depth — fits standard 18 mm pitch enclosures. ## Comparison with 5SL4363-7 The 5SL4363-7 shares the same 3-pole, C-curve, 400 V AC rating and identical mechanical footprint (76 mm depth, 54 mm width, 90 mm height) but steps up to a 10 kA breaking capacity per both EN 60898 and IEC 60947-2. If your panel fault level exceeds 6 kA, the 5SL4363-7 is the direct upgrade without re-drilling the DIN rail or re-terminating the busbar. ## Integration notes Snap-on DIN rail mount, any orientation. Sealable cover is standard for tamper-proof installations.","metaTitle":"Siemens 5SL6320-7MB SENTRON MCB, 3P C 20A 6kA","metaDescription":"Siemens SENTRON 5SL6320-7MB miniature circuit breaker, 3-pole, C-curve, 20 A, 400 V AC, 6 kA breaking capacity per EN 60898.
