The Siemens SENTRON 5SL6132-6CC is a 1-pole miniature circuit breaker with a B tripping characteristic, rated 32 A and breaking 6 kA per EN 60898 at 230/400 V AC. The B-curve means it trips magnetically between 3 and 5 times rated current — so 96 A to 160 A for a short-circuit — which suits resistive and general-purpose loads in residential and light commercial infrastructure, not motor starting where the inrush would nuisance-trip a B-curve. If the fault level exceeds 6 kA, step up to a 10 kA rated MCB like the SENTRON 5SL4 series.
This MCB occupies 1 modular width unit (18 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted, which simplifies layout in crowded panels.
Electrical environment and compliance
The operating frequency is 50/60 Hz. Maximum operating voltage is 250 V AC single-phase, 440 V AC multi-phase. It also carries a DC rating of 72 V maximum, though the primary application is AC. Vibration resistance is 50 m/s² at 25 to 150 Hz per IEC 60068-2-6, adequate for normal building installation but not for direct mounting on heavy machinery without additional damping.
