Description
Noark MCCB Ex9M1 50kA 3 pole Frame size 1
Moulded Case Circuit Breakers Ex9M TM are intended for applications in power distribution mainly. Testing according to IEC / EN 60947-2 standards ensures functions and reliability for wide variety of applications including isolation. These breakers are offered with breaking capacities from 36 kA up to extreme 150 kA. Rated impulse withstand voltage Uimp 8 kV makes it possible to use them even in system with occurrences of transient over voltage waves of high intensity, e.g. in heavy industry.
