The eco-efficient breaker platform enables a Global Warming Potential (GWP) reduction of almost 100%.
The LTA breaker uses the same technology of the well-proven Hitachi ABB Power Grids' SF6 Life Tank Breaker product range. This provides our customers with the highest reliability and the same product footprint while lowering the environmental impact.
The LTA is also available as a Disconnecting Circuit Breaker, where the disconnecting function is integrated into the breaker.
Live Tank Circuit Breaker - LTB AirPlus™
LTA makes use of a CO2-based gas mixture as the insulating and arc extinguishing medium as an alternative to SF6.
Applications
- Line, transformer, reactor and capacitor switching
- Switching of harmonic filters
Why Hitachi ABB Power Grids?
- LTA's gas mixture has a Global Warming Potential (GWP) < 1 vs 23,500 of SF6
- Close to 100% GWP reduction compared to conventional breakers
- Scalable from MV to HV in interruption and insulation technology
- A future-proof solution to comply with environmental regulation changes
- Based on well-proven high-voltage breakers technology of Hitachi ABB Power Grids
