The Siemens SENTRON 5SY6216-8 is a 2-pole miniature circuit breaker with a D tripping characteristic, rated for 400 V AC and 50/60 Hz. It breaks fault currents up to 6 kA per EN 60898 and 15 kA per IEC 60947-2, with a DC rating of 72 V and 15 kA per IEC 60947-2. The D curve means it handles high inrush currents — typical for motor, transformer, or lighting ballast loads — without nuisance tripping on startup.
IP20 with connected conductors — fine inside a sealed enclosure, not for wet locations.
Listed as current production — no phase-out or last-time-buy notice on record.
Rated for AC and DC circuits per EN 60898 and IEC 60947-2, plus UL 1077 and CSA C22.2 No. 235 (5 kA at AC). Halogen-free and silicon-free construction. Sealable for tamper-proof installations. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz; 50 m/s² at 25–150 Hz). The manufacturer provides RoHS, REACH, and CE declarations with the shipment.
