Why 8DA10-8DB10?

Siemens 8DA10 single-bus and 8DB10 double-bus switchgear are arc-resistant, gas-insulated, medium-voltage solutions. Use these designs in limited spaces, harsh environments, and to lower your total cost of ownership.

Address conventional switchgear challenges with our compact, gas-insulated designs. Our solutions are approximately 75% smaller than traditional air-insulated alternatives, freeing valuable space. They provide robust arc-resistance and environmental immunity for enhanced personnel safety.

Enjoy a maintenance-free primary part to reduce operational costs and downtime. Our arc-resistant design reduces personal protective equipment needs. The compact footprint optimizes layout and lowers building costs by allowing installation in tight spaces.

Key benefits

Improve operator safety

Reduce personal protective equipment needs with our arc-resistant design. Perform all operations safely from the front of the switchgear. Ensure a secure working environment for your team.

Reduce costs

Reduce your total cost of ownership with reduced maintenance. Our design needs minor service every 10 years and major service only once every 20 years to make your budget go further.

Operate reliably in challenging environments

Ensure consistent performance in sites with dust, vermin, salt or contaminated atmospheres. The SF6 insulation prevents derating due to altitude to maintain full operational capacity.

Featured capabilities

Arc-resistant protection to IEEE C37.20.7

Implement arc-resistant protection to IEEE C37.20.7 type 2B, up to 40 kA for 0.5 seconds. Significantly reduce personal protective equipment needs for your personnel.

Compact design

Our compact gas-insulated switchgear is up to 75 percent smaller than traditional air-insulated models. Optimize your layout and reduce building costs.

Switchgear details

Single-phase design eliminates phase-to-phase faults inside the switchgear. The vacuum interrupter performs up to 30,000 mechanical operations. Low-pressure SF6 gas-insulated for insulation only and not for interruption.
