A marine product type approved solution
In collaboration with KWx, Astrol Electronic AG developed a range of solid-state 1,5 kV DC breakers for marine applications. This unique technology provides maximum flexibility for onboard DC grids and protects against short-circuit currents in any part of the grid. Following the 0.5kA and 1.25kA DC breaker switches, that were type approved in November 2019, we proudly announce that the 3 kA DC breaker switch has also received the official DNV type approval.
The increase in DC grids onboard vessels and our answer in protecting them
Hybrid and all-electric ships become increasingly popular. To be able to support larger electrical systems, capable of integrating alternative energy sources and storage systems, DC is the onboard power distribution system of choice. This, thanks to its ability to handle large power flows in a confined space with high system efficiency and low life-cycle cost.
Protecting onboard DC grids against short-circuit currents and power overload
Our DC breaker is the answer in effectively protecting onboard DC grids. Interested in how it all started? Please check out our previous news update.
This video shows gives an overview of the DC breaker switch and how this technology enables interrupting short-circuit currents within μs.
