The smart choice for maximum availability at a low total cost
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 according Cigré report on high-voltage circuit breakers reliability, (group A3.06 October 2012), which means a low life-cycle cost.
Hitachi ABB Power Grids' 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, earth). The DCB is compliant with IEC standard 62271-108 for disconnecting circuit breakers.
