Moulded Case Circuit Breakers Ex9M
Moulded Case Circuit Breakers Ex9M TM are intended for varying applications in the sector of residential and office premises, commercial and administrative centres but also for highly demanding industrial applications. Testing according to IEC / EN 60947-2 standards ensures functions and reliability for wide variety of applications including isolation.
These breakers are offered in 3 and 4-pole versions, thermomagnetical relases, 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.
All frame sizes can be fitted with varying accessories including auxiliary and signal contacts, under-voltage and opening releases, rotary handles, motor actuators and others.
