It's rated 6 kA breaking capacity per EN 60898 and 10 kA per IEC 60947-2 at 400 V AC, with a 72 V DC maximum. Single modular width (18 mm) on DIN rail, 70 mm installation depth, 76 mm overall depth. The 6 kA rating per EN 60898 covers the residential and light commercial branch circuit fault duty. The 10 kA per IEC 60947-2 is the industrial rating — that's the number that matters when this breaker lands in a panel fed by a transformer with higher available fault current. The C-curve (trips at 5-10x rated current) is the standard choice for motor-starter and transformer inrush — not for resistive loads where a B-curve would do, but not for high-inrush drives where a D-curve is needed. Single-pole, 400 V AC line-to-line, 72 V DC maximum. At DC the arc extinction is harder; 72 V is the limit for this pole configuration. ## Panel integration Snap-on DIN rail mount, 18 mm width (1 MW). Accepts solid conductors up to 35 mm² — that's a 6 AWG equivalent, enough for the feed side on a sub-panel. Ambient range -40 to 75 °C covers unheated enclosures in cold climates and hot transformer vaults. 10 000 mechanical cycles typical — not a daily-switch duty, but fine for branch protection where it trips rarely.","metaTitle":"Siemens 5SN6163-7CP SENTRON MCB, 1-Pole C-Curve, 6 kA","metaDescription":"Siemens 5SN6163-7CP SENTRON MCB, 1-pole, C-curve, 6 kA per EN 60898, 10 kA per IEC 60947-2. 400 V AC, 72 V DC. 18 mm wide.

The 5SN6163-7CP carries a 6 kA EN 60898 rating versus the 5SL4106-7CC's 10 kA — so if the panel requires 10 kA per EN 60898, the 5SL part is the correct fit.
