The Siemens SENTRON 5SY6213-7 is a 2-pole miniature circuit breaker with C-curve tripping characteristic, rated 6 kA per EN 60898-1 and 15 kA per IEC 60947-2 at 400 V AC. It also carries a 15 kA interrupting rating at 60 V DC per IEC 60947-2, and 5 kA under UL 1077 / CSA C22.2 No.235.
The C-curve (tripping characteristic C) means the breaker holds up to 5–10× rated current for short durations before tripping magnetically — standard for motor and lighting circuits with moderate inrush. The 5 kA UL 1077 rating is for supplementary protection in North American panels — not a branch-circuit main, but fine for downstream equipment. Rated for AC operation at 400 V (multi-phase) or 440 V (single-phase), and DC up to 60 V (72 V max).
Halogen-free and silicon-free construction. Sealable terminals (top and bottom combined) allow tamper-proofing after commissioning.
