The Siemens 5SL4515-7CC is a 1+N-pole miniature circuit breaker from the SENTRON 5SL4 series, rated 1.6 A with a C-trip curve and a 10 kA breaking capacity at 230 V. That 10 kA interrupting rating means it can safely clear a fault current up to 10,000 amps without welding its contacts or cascading damage upstream — sized for residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. The C-curve (5–10× In) is the standard choice for general-purpose loads: lighting, socket outlets, small appliances. It trips fast enough on a hard short but tolerates the inrush of a motor starting or a capacitor bank charging.
Snap-on DIN rail mounting for standard 18 mm per pole width. The 1+N-pole format occupies two modules on the rail — one for the protected phase, one for the switched neutral that opens simultaneously with the phase. Rated for 230 V AC, 50/60 Hz. The 10 kA breaking capacity is the Icn per IEC 60898-1, which certifies its performance for overcurrent protection in household and similar installations.
