The Siemens 5SL6613-7YA is a 3-pole+N miniature circuit breaker (MCB) from the 5SL6 series, rated at 13 A with a C-trip curve and a 6 kA breaking capacity at 230/400 V.
Deployment context
The 3-pole+N configuration (three protected phases plus a switched neutral) suits three-phase final sub-circuits where the neutral needs isolation — common in European-style TN-S or TN-C-S systems. The neutral pole is switched but not protected, so it opens with the phases on a fault.
