No. The 5SY4140-7 is a miniature circuit breaker, not a breaker accessory. The 3VA9908-0BB15 is an undervoltage release that installs inside the 3VA breaker housing, not a standalone device — different form factor, different wiring scheme.
As a Siemens SENTRON component, it carries CE marking and is designed to IEC/EN 60947-2 accessory standards. RoHS and REACH declarations are available through the manufacturer's documentation portal.
