The Siemens 5SY4415-7CV is a 4-pole miniature circuit breaker (MCB) with a C-curve trip characteristic rated at 1.6 A. Its 15 kA rated ultimate breaking capacity (Icu) at 400 V AC means it can safely interrupt fault currents up to that level without welding its contacts or failing catastrophically — a key spec for verifying selectivity and SCCR headroom in a distribution board or panel.
