DC Breaker for Solar Power Generation

“DC Breaker for Solar Power Generation” has achieved downsizing by the technology of two-pole DC interruption. The volume ratio compared to our conventional DC breaker is 50%. It helps reduce the size of DC collection boxes as well and leads to installation of collection boxes in wider variety of places.

・Technology 1
Double-contact blade structure
Two-pole interruption has been achieved by making two contacts like a seesaw.

・Technology 2
Even contact pressure by the independent arm structure

The combined arm structure may cause electric instability due to uneven pressure on either contact. The independent arm for each of the two contacts ensures even pressure.
