The D curve means it tolerates the high inrush currents typical of motor and transformer loads — expect magnetic trip between 10× and 20× rated current, so it avoids nuisance trips on inductive starts while still clearing a hard short. ## Lifecycle and sourcing For a BOM line or a panel spare, the 5SL7304-8RC is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. ## What the ratings mean for fit The 15 kA breaking capacity at 415 V means this breaker can safely interrupt a fault current up to that level without welding its contacts or cascading damage upstream — sized for commercial and light industrial panelboards where the prospective short-circuit current stays under that threshold. The D 4 characteristic (10–20× In magnetic trip) is the deciding factor for motor branch circuits: a standard B or C curve would trip on the starting surge of a 4 A motor load; the D curve holds through the acceleration phase.","metaTitle":"Siemens 5SL7304-8RC MCB, 415V 3-pole 15kA D 4","metaDescription":"Siemens 5SL7304-8RC miniature circuit breaker, 415V 3-pole, 15kA breaking capacity, D 4 characteristic.
