The Siemens 5SY6210-7CC is a 2-pole miniature circuit breaker from the SENTRON series, rated 6 kA interrupting capacity per EN 60898 at 400 V AC. The C-curve tripping characteristic means it handles moderate inrush currents — typical for motor and lighting circuits in industrial panels. It occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm.
Snaps onto a standard DIN rail via the quick assembly system; mounting position is any. The IP20 rating (with connected conductors) is typical for enclosed panel gear — no washdown protection, so keep it inside the cabinet. Combined terminals top and bottom accept the same wire range, and the breaker is sealable for tamper-proofing. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz — fine for most industrial machinery.
Rated for overvoltage category III and pollution degree 3, so it's suited for fixed installations in industrial environments. The 1.1 W power loss per pole at rated current is low enough to avoid derating in a crowded enclosure. Mechanical service life is 10 000 operating cycles typical.
