DC MCB for 250 V rail and battery circuits
The Siemens 5SL5225-6CC is a 2-pole miniature circuit-breaker rated for 250 V DC with a 10 kA breaking capacity and a B25 trip characteristic. It's built for DC branch circuits where a standard AC MCB won't reliably interrupt a DC arc — think 250 V battery banks, UPS output feeders, or DC bus distribution in a control cabinet.
