The D16 curve means it is designed for motor and transformer loads that draw a high inrush current — the magnetic trip kicks in at 10 to 20 times rated current, so it holds through starting surges without nuisance tripping. The 15 kA breaking capacity at 230/400 V means this MCB can safely interrupt a fault current up to 15,000 amps without welding its contacts or failing catastrophically — important for installations with high prospective short-circuit current, like industrial panelboards fed by large transformers. The 1P+N configuration switches the line conductor only; the neutral is switched but not protected. This is standard for single-phase branch circuits where the neutral is solidly bonded upstream.","metaTitle":"5SY4516-8CV MCB, 15kA Icu 230/400V 1P+N D16","metaDescription":"5SY4516-8CV miniature circuit breaker, 15kA breaking capacity at 230/400 V, 1P+N, D16 characteristic.
