Baiya Energy supplies genuine Siemens Energy high-voltage circuit breakers — SF6 dead-tank (3AP-DT/DTC), live-tank (3AP), Blue Vacuum SF6-free, and gas-insulated switchgear (GIS). Every unit is IEC 62271-100 and IEEE C37.04 certified, sourced from Siemens Energy's global manufacturing network, and shipped worldwide with technical support.
Whether you need a compact dead-tank with integrated CTs for a space-constrained substation, or a fully-enclosed GIS bay for an offshore platform, there is a Siemens Energy platform sized for the job.
Grounded tank design with integrated current transformers (DTC option), spring-operated mechanism, and excellent seismic performance. The workhorse for North American utility and outback transmission sites.
Modular self-blast interrupter, maintenance-free spring drive, optional pre-insertion resistors (PIR) for long-line switching. The IEC-market standard from 72.5 kV all the way to 800 kV.
Zero SF6 emissions. Vacuum interrupter combined with clean-air insulation — fully compliant with the EU F-gas Regulation and the sustainable choice for utilities decarbonizing their switchgear fleet.
Up to 90% footprint reduction versus air-insulated switchgear. Fully enclosed, weather-sealed, maintenance-light — the go-to platform for urban substations, offshore platforms and industrial retrofits.
We do not resell white-label copies. Every breaker leaves a Siemens Energy factory and arrives on your foundation with full type-test documentation.
All products are sourced directly from Siemens Energy's global manufacturing network — including their China plant, one of two worldwide 3AP production bases.
IEC 62271-100, IEEE C37.04, and CE. Every rating type-tested at independent short-circuit laboratories with documentation shipped with each unit.
Fast shipping worldwide. Regional stocking on select 3AP-DT ratings; long-lead GIS bays project-managed end-to-end with technical support included.
A compact overview to help engineers narrow the platform in seconds. Full type-test data available on request.
