The Siemens 5SL7263-7RC is a 2-pole miniature circuit breaker rated 415 V with a 15 kA breaking capacity, C-trip curve, and 63 A current rating. The C-curve means it holds through moderate inrush (5–10× rated current) before tripping — suited for motor-starter and transformer primary protection where the load draws a brief magnetizing surge.
Deployment context
Snap-on DIN-rail mounting for standard 35 mm rail in distribution boards or sub-panels. The 2-pole form factor fits single-phase or two-leg three-phase branch circuits where a common-trip pair is required.
