Market Trend
General needs in the past New-normal needs
Apparatus by 1000Vdc, 690Vac
Manual type, low cost
Apparatus by 1000Vdc Less interest on Short-circuit
level
LVRT and HVRT for wind turbine control and power converter
1500Vdc, 900Vac for high altitude
Compact UL Listed device
Breakers for 1500Vdc, 690Vac Bigger battery, higher kA Bi-directional
Breakers up to 1150Vac Still important : LVRT/HVRT
Now markets want to have more compatible, compact and certified solution.
