The Siemens SENTRON 5SL6210-7 is a 2-pole miniature circuit breaker with C-curve tripping characteristic, rated 10 A at 400 V AC. Its 6 kA breaking capacity per EN 60898 and IEC 60947-2 is sized for residential and light commercial distribution boards where fault levels stay under that threshold. The C-curve (5–10× In) handles moderate inrush from small motor loads or capacitive lighting ballasts without nuisance tripping.
Snaps onto standard 35 mm DIN rail; occupies 2 modular width units (36 mm). Depth of 76 mm (70 mm installation depth) fits standard distribution board enclosures with cover clearance. IP20 with connected conductors — suitable for enclosed panel mounting, not for wet or outdoor locations. Mounting position any, which simplifies layout in tight enclosures. Sealable design allows the installer to lock the handle position after commissioning.
Rated for 50/60 Hz supply, overvoltage category III, pollution degree 2 — the standard specification for fixed-installation distribution boards. Power loss of 1.3 W per pole at rated current in hot state is low enough to ignore thermal derating in a populated enclosure. Mechanical service life 10 000 operating cycles typical. Accepts supplementary devices (auxiliary switches, shunt trips, alarm contacts) for remote status or emergency shutdown integration.
