Electronic Moulded Case Circuit Breakers Ex9M6 are intended for applications mainly in power distribution. Advantage of the electronic release is in an accuracy and reliability of the tripping contrary to the thermomagnetic release. 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 50 kA up to 100 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.
Utilization category B circuit breakers.
