The EA8DC series is a range of dedicated DC MCCBs (circuit breakers) designed specifically for use in DC power grid circuits. These circuit breakers are engineered to operate within a rated voltage range of DC 250V to DC 1500V and a rated working current range of 63A to 800A. They are primarily utilized for electrical distribution and protection in photovoltaic (PV) systems and other DC power applications.

 

The EA8DC series circuit breakers offer comprehensive protection functions, including overload long delay and short-circuit instantaneous protection. These features ensure that the circuit breakers can effectively distribute electricity, safeguarding the integrity of electrical lines and protecting power equipment from overload, short circuits, and other potential fault hazards.

 

In terms of standards compliance, the EA8PV series DC MCCBs adhere to the requirements outlined in IEC 60947-1 and GB/T14048.1 for general provisions. These standards define the general principles and guidelines for low-voltage switchgear and controlgear, ensuring the safety, performance, and reliability of electrical equipment. Additionally, the circuit breakers meet the specifications of IEC 60947-2 and GB/T14048.2, which specifically address the requirements for circuit breakers.

 

By conforming to these international standards, the EA8DC series circuit breakers guarantee the quality, safety, and performance expected in DC power grid applications. They are engineered to provide reliable protection against various electrical faults, ensuring the smooth operation of PV systems and other DC installations.

 

To summarize, the EA8DC series of photovoltaic dedicated DC MCCBs are specifically designed for use in DC power grid circuits. With a wide voltage and current range, these circuit breakers offer comprehensive protection functions to safeguard electrical lines and power equipment from overload, short circuits, and other fault hazards. Compliant with international standards such as IEC 60947-1, GB/T14048.1, IEC 60947-2, and GB/T14048.2, the EA8DC series circuit breakers ensure the quality, safety, and performance required for reliable operation in photovoltaic systems and other DC power applications.
