The Siemens SENTRON 5SY6503-8CC is a 1P+N miniature circuit breaker with a D tripping curve, rated at 3 A and 6 kA breaking capacity per EN 60898.
Rated 6 kA according to EN 60898 at 230 V AC, and 5 kA per UL 1077 and CSA C22.2 No. 235. The part also carries an overvoltage category III rating and pollution degree 3, so it's rated for fixed installations inside enclosures where transients and dust are a given.
Terminal screws are sealable for tamper-proofing.
It is rated 6 kA per EN 60898 at 230 V AC, and 5 kA per UL 1077 and CSA C22.2 No. 235.
The SENTRON 5SY4101-7CV shares the same 1P+N pole configuration and 2-module width, but uses a B tripping curve instead of D. The D curve on the 5SY6503-8CC handles higher inrush currents, so swapping to a B-curve part may cause nuisance tripping on inductive loads.
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit a request for a firm offer.
The part carries UL 1077 and CSA C22.2 No. 235 approvals, plus EN 60898 certification. RoHS and REACH compliance are standard for Siemens SENTRON products, but specific declarations can be provided with the order documentation.
