The D-curve means it tolerates the high inrush currents typical of motor and transformer loads — expect magnetic trip between 10x and 20x rated current, so it holds through a soft-start or direct-on-line start without nuisance tripping. At 15 kA breaking capacity, this MCB safely interrupts a fault current up to that level at 415 V AC, which covers most industrial panel secondary-side protection and distribution sub-feeders. Snap-on DIN-rail mount for standard 35 mm rail — fits alongside other 5SL series breakers in a distribution board or control panel enclosure. ## Lifecycle and Sourcing For BOM-line commitment, the 5SL7406-8RC is sourced and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.","metaTitle":"Siemens 5SL7406-8RC Miniature Circuit Breaker, 415V 4P 15kA","metaDescription":"Siemens 5SL7406-8RC miniature circuit breaker, 415V 4-pole, 15kA breaking capacity, D-curve 6A.
