Breaking capacity is 15 kA per EN 60898 and 20 kA per IEC 60947-2, so it clears high-fault currents in industrial distribution without cascading upstream. The 18 mm width per pole (3 modular units total) snaps onto a standard DIN rail, and the 76 mm depth leaves room for wiring behind the gland plate. ## Where it fits — panel integration and environment Vibration-rated per IEC 60068-2-6, which matters for machine-mounted sub-panels on conveyors or compressors. ## Compliance and documentation signals Sealable design allows lockout/tagout. The Betagard brand is Siemens' value line for commercial and light industrial panels, distinct from the SENTRON residential range.","metaTitle":"Siemens Betagard 5SL7306-8RC MCB, 3P D 6A, 15kA EN 60898","metaDescription":"Siemens Betagard 5SL7306-8RC miniature circuit breaker, 3-pole, D-curve, 6 A, 415 V AC, 15 kA (EN 60898) / 20 kA (IEC 60947-2).

Both are 3-pole, same depth (76 mm) and height (90 mm), same DIN-rail mounting. The key difference is the D-curve vs C-curve and the higher breaking capacity on the Betagard (15/20 kA vs 10 kA). No rewiring needed for the busbar or load connections, but verify the trip curve matches your load type."},{"question":"Where can I buy 5SL7306-8RC?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
