Ex9M5N SU20S 800 4P4T
Moulded Case Circuit Breakers Ex9M with SU20S type of smart unit are intended for applications in power distribution mainly. Testing according to IEC / EN 60947-2 standards ensures the functionality and reliability for wide variety of applications including isolation. The electronic controller with LCD display allows a detailed and accurate commission of the device for the installation requirements. Electronic technology improves the stability of the device on applications with signifi cative mechanical stress. These breakers are off ered with breaking capacities from 36 kA up to extreme 150 kA. Rated impulse withstand voltage Uimp up to 12 kV makes it possible to use them even in system with occurences of transient overvoltage waves of high intensity, e.g. in heavy industry. Utilization category A and B circuit breakers.
