What the ratings mean for fit
The 5SL4163-7RC is a 1-pole SENTRON miniature circuit breaker rated 63 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898 at 415 V AC. The C-curve (5–10× In) is the standard choice for general-purpose branch circuits feeding resistive and moderate inductive loads — lighting, small transformers, control power supplies — where inrush is modest but not negligible. The 10 kA SCCR at 415 V means it safely clears a fault up to that level without upstream coordination failure, which is typical for residential and light commercial distribution boards. The single-pole form factor occupies one modular width unit (18 mm) on a DIN rail, so it fits a standard 18 mm slot in any SENTRON distribution panel.
Deployment context
Rated for residential buildings and infrastructure, this breaker mounts in any position on a DIN rail with an installation depth of 70 mm. The IP20 rating (with connected conductors) means it is protected against finger contact but not against moisture — suitable for indoor distribution boards, not outdoor or washdown environments. The 76 mm depth matches standard SENTRON enclosures; no panel rework needed for a drop-in replacement.
