DISCONNECTING CIRCUIT BREAKER

EconiQ™ Disconnecting Circuit Breaker LTA

Disconnecting Circuit Breaker DCB up to 550 kV

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

The smart choice for maximum availability at a low total cost

The EconiQ DCB LTA 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.

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

EconiQ is Hitachi Energy’s eco-efficient portfolio for sustainability where products, services and solutions are proven to deliver exceptional environmental performance.

A Disconnecting Circuit Breaker (DCB) provides the functionality of a circuit breaker and a disconnector combined in a single unit.

Without the need for separate disconnectors, up to 75 percent less space is required. Unplanned outages are reduced by up to 70 percent, which means a low life-cycle cost.

Hitachi Energy’s DCB is ideal for all substation applications – indoor, outdoor, greenfield or refurbishment. It offers the highest level of safety with the easily operated robust mechanical and electrical interlocking that supports the five golden safety steps for high voltage operations (interrupt, isolate, lock, voltage check and earth). The DCB is compliant with IEC standard 62271-108 for disconnecting circuit breakers
