Siemens 5SL7406-8RC — 4-Pole MCB, 415 V, 15 kA, D 6
The Siemens 5SL7406-8RC is a 4-pole miniature circuit breaker rated 415 V with a 15 kA breaking capacity and a D-curve trip characteristic set at 6 A. 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
