A DCB provides the functionality of a circuit breaker and a disconnector combined in a single unit. Without the need for separate disconnectors, up to 65% less space is required. Hitachi ABB Power Grids' DCB is suitable for outdoor and indoor substation applications.
The DCB is also available as an eco-efficient alternative, the DCB LTB AirPlus™, which uses AirPlus gas-mixture as the insulating and arc extinguishing medium.
The eco-efficient breaker platform enables a Global Warming Potential (GWP) reduction of almost 100%.
