DC Moulded Case Circuit Breakers Ex9MD TM are intended mainly for photovoltaic applications. Testing according to IEC / EN 60947-2 standards ensures functions and reliability for wide variety of applications including isolation. These breakers are off ered with breaking capacities from 25 kA up to 100 kA. Rated impulse withstand voltage Uimp 8 kV makes it possible to use them even in systems with occurences of transient overvoltage waves of high intensity.
