Its 15 kA breaking capacity per EN 60898 (20 kA per IEC 60947-2) at 415 V AC means it handles moderate fault currents typical of industrial panel feeders — enough to clear a bolted fault on a 200 kVA transformer secondary without upstream coordination issues.
Betagard vs SENTRON — what the brand badge means
This Betagard 5SL7310-7RC shares the same 76×90 mm footprint and 3-pole C-curve design as the SENTRON 5SL4363-7, but the Betagard carries higher interrupting ratings: 15 kA vs 10 kA under EN 60898, and 20 kA vs 10 kA under IEC 60947-2. The SENTRON sibling is rated for residential/infrastructure duty; the Betagard is explicitly marked for industry (Overvoltage Category III, Pollution Degree 2). The physical drop-in is identical: same DIN-rail clip, same terminal spacing, same 70 mm installation depth.
Current production. Betagard line is Siemens' industrial MCB range, actively manufactured.
Installation notes
IP20 with connected conductors — install inside a closed panel. Sealable, halogen-free and silicon-free (–), so it's safe for clean-room or food-bev environments where outgassing contaminants must be avoided. Terminal design accepts standard copper conductors up to the rated cross-section; no special lug kit needed. Vibration-resistant per IEC 60068-2-6, rated for 10 000 mechanical operating cycles typical.
