It occupies 4 modular width units (72 mm) on a DIN rail, making it a direct fit for standard residential and infrastructure distribution boards where a switched neutral is required. ## What the ratings mean for fit The C-curve (tripping characteristic class C) means the breaker trips at 5 to 10 times rated current — suited for circuits with moderate inrush, like lighting banks or small motor loads, without nuisance tripping on startup. The 6 kA breaking capacity at 400 V AC (per EN 60898) tells you it can safely interrupt a fault current up to that level; for installations with higher prospective fault current, you'd need a breaker with a higher rating or upstream current-limiting device. The 3-pole+N design switches all three phases and the neutral, which is required in TN-S or TT systems where the neutral must be disconnected for isolation. The neutral pole is switched but not protected — overcurrent protection is on the phase poles only. Rated for overvoltage category III and pollution degree 2, this MCB is specified for fixed installations inside a distribution board — not for outdoor or wet locations. The IP20 rating (with connected conductors) confirms it's touch-safe only when installed in an enclosure. ## Panel integration and mounting Snap-on mounting to DIN rail, any position. Depth is 76 mm (70 mm installation depth), width 72 mm (4 MWUs). The 90 mm height is standard for SENTRON 5SL series, so it aligns with adjacent breakers and busbars in a distribution board. Sealable, halogen-free, silicon-free — suitable for installations with material restrictions (e.g., healthcare, marine). Supplementary devices (auxiliary switches, shunt trips, alarm contacts) can be installed on the right side — the product extension feature is supported, so you can add remote signaling or trip indication without replacing the breaker.","metaTitle":"Siemens 5SL6603-7CC SENTRON MCB, 3P+N, C-Curve, 3A, 6kA","metaDescription":"Siemens 5SL6603-7CC SENTRON miniature circuit breaker, 400V AC, 6kA breaking capacity, 3-pole+N, C-curve, 3A.
