It is designed for DC branch-circuit protection in residential and infrastructure applications, with a breaking capacity of 10 kA. The C-curve means it trips between 5 and 10 times rated current, suited for moderate inrush loads like lighting banks or small DC power supplies where you need to ride through the start-up pulse without nuisance trips. ## DC rating and what it means for fit This breaker is rated for DC circuits up to 125 V, which is the maximum voltage per pole. In a DC system, arc extinction is harder than AC because there is no natural zero-crossing, so the 10 kA breaking capacity at 125 V DC is the relevant fault-interruption figure — not the AC rating. If your BOM calls for DC protection at this voltage and current, the 5SL5132-7CC is dimensioned for it. The single-pole form factor (18 mm width, one width unit) snaps onto standard DIN rail and occupies one slot in a distribution board. ## Integration and environment Mounts in any position on DIN rail, with an installation depth of 70 mm and overall depth of 76 mm. The housing is IP20 with connected conductors — finger-safe terminals but not sealed against moisture, so it belongs inside a panel or enclosure, not in a washdown zone. Rated for ambient temperatures from -40 °C to 75 °C, covering most indoor and sheltered outdoor enclosures. Pollution degree 2 and overvoltage category III are standard for fixed-installation distribution boards.","metaTitle":"Siemens 5SL5132-7CC SENTRON MCB, 1P, C-Curve, 32A, 125V DC","metaDescription":"Siemens 5SL5132-7CC SENTRON miniature circuit breaker, 1-pole, C-curve, 32A, 125V DC, 10kA breaking capacity.
