Its headline rating is the 15 kA interrupting capacity (Icu) at 400 V AC — that means it can safely clear a fault current up to 15,000 amps without welding its contacts or rupturing the case. For a panel builder, that 15 kA figure is the one that decides whether this breaker coordinates with the upstream transformer or main breaker; if your available fault current at the panel is 14 kA, this holds. If it's 16 kA, you need a higher-rated device. ## Where it fits This MCB snaps onto a standard DIN rail inside a distribution board or control panel. The D-curve (10–20× In magnetic trip) is sized for loads with a high inrush — think motor starters, small transformers, or welding equipment — where a B or C curve would nuisance-trip on the start-up current. Two-pole configuration means it switches both line conductors, used on single-phase circuits or on the line side of a two-phase sub-distribution.","metaTitle":"Siemens 5SY4213-8CV MCB, 15kA 400V 2P D13","metaDescription":"Siemens 5SY4213-8CV miniature circuit breaker, 15kA interrupting capacity at 400V, 2-pole, D13 curve.
