The Siemens SENTRON 5SL6325-7RC is a 3-pole miniature circuit breaker rated 25 A with a C tripping characteristic. It provides 7.5 kA breaking capacity per EN 60898 at 415 V AC, making it a standard choice for residential and light commercial distribution boards where moderate fault currents are expected.
Fit and footprint
Occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and 70 mm installation depth behind the panel. Mounts in any position. The IP20 rating (with connected conductors) means it's intended for enclosed distribution boards, not washdown areas.
What the ratings mean
The C characteristic means the magnetic trip operates at 5 to 10 times rated current — suited for mixed resistive and moderate inductive loads like lighting circuits, small motors, and general-purpose outlets. The 7.5 kA breaking capacity tells you it can safely interrupt a fault current up to that level at 415 V AC without welding contacts or cascading failure upstream. Rated for 50/60 Hz supply, overvoltage category III, pollution degree 2 — standard for fixed-installation switchgear.
