That 15 kA rating is the same under both standards, so it holds up for industrial fault levels without needing a separate current-limiting fuse upstream — one less thing to coordinate on a panel schedule. D-curve means the magnetic trip fires between 10x and 20x In — 250 A to 500 A instantaneous. That's sized for transformer inrush, motor starting, or welding loads where a C-curve would nuisance-trip on the first half-cycle. If your circuit has a high inrush load that keeps popping a C-curve, this is the swap. Rated for 415 V AC, maximum operating voltage 440 V AC in single or multi-phase operation. Frequency 50/60 Hz. Power loss per pole is 2.4 W at rated current in hot state — 4.8 W total for the 2-pole unit. That's low enough to stack adjacent breakers without derating in a standard enclosure, but worth checking if you're packing 20+ breakers in a small sub-panel with no ventilation. Vibration resistant per IEC 60068-2-6. Sealable, halogen-free, silicon-free — suitable for environments where outgassing or contamination matters, like clean rooms or sealed enclosures near sensitive electronics.","metaTitle":"Siemens Betagard 5SL7225-8RC MCB, 2P D 25A 15kA 415V","metaDescription":"Siemens Betagard 5SL7225-8RC miniature circuit breaker, 2-pole, D-curve, 25A, 15kA breaking capacity at 415V AC.

That's the same figure under both standards, so it's suitable for industrial fault levels without upstream current-limiting fuses."},{"question":"Will 5SL7225-8RC drop into a panel specified around 5SL6120-7?","answer":"Not without rewiring. The 5SL6120-7 is a 1-pole C-curve unit on a single 18 mm module; this is a 2-pole D-curve on two modules. Same depth (76 mm) and height (90 mm), but the pole count, trip curve, and width are different. The panel would need a different busbar arrangement and possibly a larger enclosure gutter."},{"question":"Where can I buy 5SL7225-8RC?","answer":"Sourced and quoted to order against an RFQ through independent distribution channels.
