Rated 10 A at 230 V AC with a C-curve tripping characteristic, meaning it is designed for moderate inrush loads like small motors, lighting banks, and transformer primaries — the magnetic trip threshold sits at 5 to 10 times rated current, so it holds through a short motor start but clears a hard fault fast. Breaking capacity is 6 kA per EN 60898 and IEC 60947-2, which covers the typical prospective fault level at the sub-distribution level in most commercial and residential panels — no need to uprate unless you are close to a large transformer. Occupies 2 modular width units (36 mm) on a DIN rail, with a 76 mm depth that clears most standard enclosure gland plates and busbar shrouds — the 70 mm installation depth means it fits into shallow backboxes without forcing the door. Rated IP20 with connected conductors — that is the standard for inside a distribution board; no special sealing required as long as the enclosure door is closed. ## Thermal derating — the number that matters for real loads The 10 A rating holds at 30 °C ambient; at 40 °C it derates to 9.24 A, at 45 °C to 8.8 A, and at 55 °C to 7.96 A — if the panel sits in a hot machine room or a sun-exposed cabinet, size the upstream load accordingly or step to the next higher amp rating. Ambient conditions include periodic exposure to +55 °C with up to 95 % humidity — this MCB is rated for the condensation-prone environments you find in tropical installations or unheated electrical rooms. Designed to EN 60898 and IEC 60947-2, with overvoltage category III and pollution degree 2 — suitable for fixed-installation distribution boards in residential and infrastructure buildings.","metaTitle":"Siemens 5SL6510-7BB SENTRON MCB, 2-pole C-curve 10 A 6 kA","metaDescription":"Siemens SENTRON 5SL6510-7BB miniature circuit breaker, 2-pole 1P+N, 10 A rated, C-curve, 6 kA breaking capacity per EN 60898.
