It is designed for final branch-circuit protection in residential and light infrastructure panels — think lighting, general-purpose outlets, and small appliance circuits where moderate inrush (motors, transformers, LED drivers) is expected. Breaking capacity is 4.5 kA per both EN 60898 and IEC 60947-2, which covers the vast majority of residential and light commercial service-entrance fault levels in 230 V AC networks. The 3 A rating is a common choice for lighting sub-circuits or control transformers — not for high-current feeders. The 1P+N configuration switches the phase and disconnects the neutral, which is typical for single-phase final circuits in many European wiring rules.","metaTitle":"Siemens 5SL3503-7 SENTRON MCB, 2-pole C-curve 3 A, 4.5 kA","metaDescription":"Siemens 5SL3503-7 SENTRON miniature circuit breaker, 2-pole 1P+N, C-curve 3 A, 4.5 kA breaking capacity per EN 60898.
