Noark circuit breaker, surge protection devices, fuses and isolators

Noark provides a range of circuit breakers, surge protection devices, fuses and isolators for both grid and off-grid photovoltaic systems. Tested under severe lab conditions, with ambient temperatures from -25 to +70°C including a complete range of compensation curves for different temperate and elevation curves, this range of products combines streamlined structural design and electric emulation technology.

The Ex9B has current-limiting performance, which is beyond the IEC60898-1 requirement. When a short occurs, the Ex9B is claimed to reduce the thermal effects of the cable to ensure the safety of the electrical system and prolong the life of the circuit breaker.

The Ex9M moulded case circuit breaker is widely used in electrical power systems. It provides protection for circuits and electrical equipment in overload, short-circuit, and under-voltage situations. The circuit breaker deviates from traditional linear forms and instead features a gentle arc at the front.

The MCB Ex9BP for PV is made from premium quality plastic and metals to ensure reliability. Noark conform to all relevant international standards including SAA.
