The 15 kA Icu at 400 V is the ultimate breaking capacity — the breaker can interrupt one fault at that level and still hold voltage afterward (though it may need replacement after the event). ## Panel integration Snap-on DIN rail mounting, standard 1P+N module width. Busbar compatible via the comb-bridge slots on the line side. The neutral terminal is on the right-hand pole; verify the busbar pitch matches your distribution block before wiring.","metaTitle":"Siemens 5SY4550-7CV MCB, 1P+N C50, 15kA Icu","metaDescription":"Siemens 5SY4550-7CV miniature circuit breaker, 1P+N, C-curve 50A, 15kA Icu at 230/400V.
