It carries a 6 kA breaking capacity per EN 60898 and 10 kA per IEC 60947-2 — the IEC 60947-2 figure is the one that governs industrial panel SCCR calculations, so that 10 kA rating is the number to use when coordinating with upstream protection in a distribution board. Occupies 3 modular width units (54 mm) on a standard DIN rail, with a depth of 76 mm and installation depth of 70 mm — the same footprint as the 5SL and 5SJ series, so it drops into an existing SENTRON panel without rewiring or re-spacing. For a panel feeding motor control centers or variable-frequency drives, the 10 kA IEC 60947-2 rating is the one that determines SCCR headroom and selectivity with upstream molded-case breakers. Current production. Quoted to order against RFQ through independent distribution.","metaTitle":"Siemens 5SN6350-8CP SENTRON MCB, 3-Pole, C-Curve, 6 kA","metaDescription":"Siemens 5SN6350-8CP SENTRON miniature circuit breaker, 3-pole, C-trip curve, 6 kA per EN 60898, 10 kA per IEC 60947-2, 400 V AC, 50 Hz.
