The Siemens 5SY4101-7CC is a 1-pole SENTRON miniature circuit breaker with a C tripping characteristic, rated 10 kA interrupting capacity per EN 60898 at 400 V AC.
The breaker carries approvals per EN 60898 and UL 1077 / CSA C22.2 No. 235, with a 5 kA interrupting rating under the UL/CSA standard.
Integration Notes
The 18 mm width (1 modular unit) and 76 mm depth fit standard DIN-rail enclosures. The quick assembly system and combined top/bottom terminals simplify wiring. The breaker is sealable, which allows panel builders to lock the handle position for compliance with lockout/tagout procedures. Supplementary devices (e.g., shunt trips, auxiliary contacts) can be installed on the unit.
