The C-curve means it trips between 5 and 10 times rated current, so it handles moderate inrush from small motor or lighting loads without nuisance tripping, but clears a hard short fast enough for the 3 kA fault level. No neutral pole to switch; this is a line-side only break. The 3 kA breaking capacity per EN 60898 is the rated short-circuit capacity for this MCB at 240 V AC — it will safely interrupt a fault current up to 3 kA without welding contacts or cascading failure upstream. The overvoltage category 3 rating means it's suitable for fixed-installation distribution boards, not just final circuits. Energy limiting class 3 indicates it restricts let-through energy during a fault, which helps with downstream coordination.","metaTitle":"SENTRON 5SQ2170-0KA15 MCB, 1-Pole C 15 A, 3 kA","metaDescription":"SENTRON 5SQ2170-0KA15 miniature circuit breaker, 1-pole, C-curve, 15 A rated current, 3 kA breaking capacity per EN 60898, 240 V AC.
