100887 Moulded Case Circuit Breakers Ex9M1S TM AC20 3P

EAN: 8592765008886

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 off ered 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 occurences of transient overvoltage waves of high intensity, e.g. in heavy industry.
