In a panel fed by a transformer with, say, a 10 kA prospective short-circuit current at the distribution board, this breaker has headroom; it won't need an upstream current-limiting fuse to protect it. The D-curve (10–20× In magnetic trip) means it's intended for loads with a high inrush, like small motors, transformers, or solenoid banks — a standard B- or C-curve would nuisance-trip on startup. Snap-on DIN rail mount, standard 2-pole width (36 mm). In a typical distribution board or control panel, it occupies two adjacent 18 mm slots. The D-curve and 1.6 A rating make it a natural fit for a small motor branch circuit or a control transformer primary — places where the load's startup current would trip a faster curve. The 15 kA Icu at 400 V means it's suitable for installation downstream of a main breaker or fuse with a lower interrupting rating, as long as the prospective fault current at its location doesn't exceed 15 kA.","metaTitle":"Siemens 5SY4215-8CV MCB, 15kA 400V 2P D1.6, Current Producti","metaDescription":"Siemens 5SY4215-8CV miniature circuit breaker, 15kA breaking capacity at 400V, 2-pole, D-curve, 1.6A.
