Siemens 5SL7406-7RC MCB, 415V 4-pole 15kA C-6

The Siemens 5SL7406-7RC is a miniature circuit breaker rated 415 V, 4-pole, with a 15 kA breaking capacity and a C-curve trip characteristic at 6 A. The C-curve means it trips between 5 and 10 times rated current — standard for motor and lighting circuits where moderate inrush is expected without nuisance tripping. The 15 kA short-circuit capacity at 415 V is the fault level it can safely interrupt without upstream devices needing to clear the fault first, which matters for panel coordination in a distribution board.
