The Siemens 3VA9987-0TG10 is a SENTRON T connector accessory designed for the 3VA molded-case circuit breaker family. It serves a communication and measurement function, allowing the breaker to interface with monitoring or control systems for power data collection and remote status.
Mounting and integration
Mounts in any position — no restriction on orientation, which simplifies panel layout when the connector needs to route cabling in tight enclosures. Snaps onto the 3VA breaker's accessory slot; no additional DIN-rail footprint consumed beyond the breaker itself.
