The Siemens 5SL6163-7RC is a 1-pole SENTRON miniature circuit breaker rated 63 A with a C tripping characteristic and a 7.5 kA breaking capacity according to EN 60898. At 63 A it handles a single-phase 230 V branch circuit up to roughly 14.5 kW resistive, or a 250 V single-phase motor circuit within the 7.5 kA fault-current limit.
Panel integration and add-ons
The SENTRON design accepts installable supplementary devices — shunt trips, under-voltage releases, auxiliary contacts — that clip onto the left side without increasing the 18 mm width. Sealable terminals are standard, which matters for utility-metering applications where tamper evidence is required. Halogen-free and silicon-free construction means no corrosive off-gassing during a fault, a consideration for sealed enclosures or sensitive electronics sharing the same cabinet.
