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 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.
