The C-curve means it trips between 5 and 10 times rated current — suited for inductive loads like small motors or lighting banks where inrush is moderate, not for high-surge transformer primaries (that would call for a D-curve). Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2 — that is the maximum prospective fault current the breaker can safely interrupt at 400 V AC. For a residential or light-commercial distribution board fed by a transformer with a known fault level under 6 kA, this holds. If the available fault current at the panel exceeds 6 kA, you need a higher-rated breaker or a current-limiting upstream device. Temperature derating is published: 32 A at 30 °C, 29.56 A at 40 °C, 28.16 A at 45 °C, 25.48 A at 55 °C. If the breaker sits in a warm enclosure — near other heat sources or in a non-ventilated panel — use the 40 °C or 55 °C column to size the load. The 2.3 W power loss per pole at rated current adds up; 4.6 W total for the two poles needs to be dissipated inside the enclosure. ## Mounting and integration Width is 36 mm (2 modular units), depth 76 mm, installation depth 70 mm. Mounts on a standard DIN rail in any position — vertical, horizontal, or flat — per the any-position rating. IP20 with connected conductors means it is protected against finger contact but not against moisture; keep it inside a closed panel or enclosure rated for the environment. Sealable — the breaker accepts a seal or lock to prevent unauthorized toggling, useful for safety circuits or critical loads. Supplementary devices (auxiliary contacts, shunt trips, alarm switches) are installable, so you can add remote status or trip indication without replacing the breaker.","metaTitle":"Siemens 5SL6232-7BB SENTRON MCB, 2-Pole C-Curve 32 A, 6 kA","metaDescription":"Siemens 5SL6232-7BB SENTRON miniature circuit breaker, 2-pole, C-curve, 32 A rated at 400 V AC, 6 kA breaking capacity per EN 60898.
