LTA Disconnecting Circuit Breaker, EconiQ™

The eco-efficient Disconnecting Circuit Breaker (DCB) utilizes a game-changing technology as an alternative to SF6.

The LTA DCB, EconiQ combines the functionality of an eco-efficient circuit breaker and a disconnector in a single unit while reducing the footprint by up to 65 percent. This solution is suitable for both outdoor and indoor substation applications.

LTA DCB,  EconiQ is operating with an eco-efficient CO2-based gas mixture, which essentially eliminates the CO2 equivalent emissions of the insulation medium compared to SF6 gas.

Our tool www.dcbsubstations.com allows you to evaluate the space and the cost savings by comparing a DCB solution with an array of traditional substations designs.

EconiQ is Hitachi ABB Power Grids' eco-efficient portfolio for sustainability where products, services and solutions are proven to deliver exceptional environmental performance.
