Ex9M3HVN TM 400 3P

Moulded Case Circuit Breakers Ex9MHV Thermo-magnetic (TM) type are intended for applications in power distribution with nominal voltages up to 1140V AC. These breakers are based on the regular Ex9M series and are developed to provide all the required protections to installation with an unusual higher voltage, for example: 800V AC photovoltaic installations. Testing according to IEC/EN 60947-2 standards ensures the functionality and reliability for wide variety of applications including isolation. These breakers are offered with breaking capacities from 36 kA up to 50 kA at 800V AC. High rated impulse withstand voltage makes it possible to use them even in system with occurences of transient overvoltage waves of high intensity, e.g. in heavy industry.
