Noark’s DC Moulded Case Circuit Breakers Ex9MD Thermo-magnetic (TM) mccb adj iconare intended mainly for photovoltaic applications. Testing according to IEC / EN 60947-2 standards ensures functionalities and reliability for wide variety of applications including isolation.

The MCCB have breaking capacities from 25kA up to extreme 100kA. The high rated impulse-withstand voltage (Uimp) makes them suitable even in systems with occurrences of transient overvoltage waves of high intensity, such as in heavy industry.

You can set the MCCB to your required current rating: 0.7 = 70%, 0.8 = 80%, 0.9 = 90%, 1.0 = 100% of Nominal.
