GM-SG CB
GM-SG circuit-breakers bring proven IEEE/ANSI performance up to 63 kA - with simplified maintenance, universal spare interchange and low lifecycle costs.
Why SION 3AE3 vacuum circuit-breakers?
Imagine you could build medium-voltage switchgear for IEEE/ANSI applications using only 80 % of the usual space typically used for circuit-breakers. That vision now becomes reality: The Siemens SION 3AE3 vacuum circuit-breaker comes with an extremely compact design and can be integrated quickly and easily into almost any air-insulated medium-voltage switchgear panel.
- up to 27 kV
- up to 40 kA
- up to 4000 A

Space maximizer
Reclaim 20 % of your panel space for efficient installation.
Seamless integration
Tailored for stationary or withdrawable setups, adapting perfectly to your panel's needs.
Trusted performance
Superior switching performance in compliance to latest IEEE/ANSI standards, approved by UL and CSA.
Fully customizable switching device
The SION 3AE3 can be used as a stationary operator, while any withdrawable mechanisms, primary contacts and other interfaces can be individually provided by the panelbuilder. Customers can choose between different pole-center distances (PCD) that are available for almost all voltage and current ratings.
Complete withdrawable solution
There is also a selected range of withdrawable devices available, where the SION 3AE3 is being mounted onto a compact withdrawable part, that moves the switching device from the DISCONNECT/TEST to the CONNECT position. The connection to the bus bars/fixed contacts of the panel is done with the included primary contacts.
Sustainable energy distribution with SION
Innovative vacuum technology makes SION circuit breakers robust, compact and sustainable. Siemens Product Manager Daniel Pröhl provides insights into SION circuit-breaker technology.
