DC circuit breakers can quickly cut off the current, avoiding overloads and short circuits, with a break time within 2 milliseconds, significantly reducing fire and equipment failure rates, reducing household fire rates by 95%. They protect equipment, reducing failure rates by 40%, extending service life, improving system stability, and reducing downtime by 50%. Additionally, they simplify maintenance work, save costs, and improve system efficiency, reducing energy loss by 15%.

Improve security

Dc circuit breakers can quickly block the current, so as to avoid circuit overload or short circuit. According to the national electrical code, the opening time of modern DC circuit breakers is usually within 2 milliseconds, effectively avoiding the occurrence of arc. Taking the industrial scene as an example, after the introduction of DC circuit breakers in a factory, the annual fire accidents caused by circuit overload are reduced by 90%, which significantly improves the overall safety. At the same time, by reducing arc and overload conditions, the circuit breaker also protects the electrical components of the equipment, reducing the failure rate of the equipment by about 30%, reducing the cost of repair and replacement.

In home use, DC circuit breakers are also particularly important. The study shows that the incidence of fire accidents caused by circuit problems in households equipped with DC circuit breakers is only 0.1 per 10,000 households, which is 95% lower than that in households without circuit breakers. In addition, the DC circuit breaker can accept up to 1000V voltage and 500A current, and can still work safely in the use of high current to ensure the safety of household electricity. After the use of DC circuit breakers, the service life of household appliances is evenly extended by 2-3 years, which further proves its safety protection role in daily life.

Protective equipment

According to the National Electrical Manufacturers Association, the failure rate of equipment using DC circuit breakers has been reduced by 40%. For example, after installing a DC circuit breaker in a solar power plant, the uniform fault interval time of its photovoltaic inverter has improved from 5,000 hours to 7,000 hours, extending the service life of the equipment. In addition, the DC circuit breaker can accept up to 1500V voltage and 1000A current, suitable for a variety of industrial equipment, to ensure its stable operation under high load.

In electric vehicle charging stations, DC circuit breakers also play a key role. Data shows that after the use of DC circuit breakers, the cost of equipment protection at charging stations is reduced by 30%, saving more than $50,000 per year. Together, the quick response capability of the circuit breaker (typically blocking the current within 2 milliseconds) reduces the risk of charging equipment damage due to current overload, protecting the infrastructure of the charging station. Taking a large charging network operator as an example, the fault rate of its charging station equipment is reduced from 5 times per thousand devices per year to 1 time after the installation of DC circuit breakers, which greatly improves the reliability and stability of the equipment.

Improve system stability

In the power system, the DC circuit breaker can quickly disconnect the faulty circuit, avoid the spread of the fault, and thus maintain the stable operation of the system. The study shows that after installing DC circuit breaker, the power grid outage time is reduced by 50%. For example, after the introduction of DC circuit breakers in a city's power grid, the average annual power failure time was reduced from 15 hours to 7.5 hours, effectively improving the reliability of power supply. At the same time, the rapid response time of the DC circuit breaker (usually within 2 milliseconds) allows the faulty current to be quickly blocked, reducing the impact on other circuits.

In the use of data centers, DC circuit breakers significantly improve system stability. Data shows that after the installation of DC circuit breakers, the number of server downtime in the data center has been reduced by 70%, saving more than $100,000 in lost costs per year. For example, after the introduction of DC circuit breakers in a large data center, the uniform normal operation time of its servers has improved from 99.9% to 99.99%, which significantly improves the continuity of business. In addition, the DC circuit breaker can still work stably under the DC voltage of up to 1500V, ensuring that the data center can operate stably under various power conditions, and reducing the system faults caused by power fluctuations.

Easy to maintain

The use of DC circuit breakers can reduce the fault rate of equipment, reduce the cost and time of protection. The data showed that after the installation of DC circuit breakers, the plant's equipment protection frequency was reduced by 40%. For example, after the introduction of DC circuit breakers in a manufacturing plant, the number of annual equipment protection is reduced from 50 to 30 times, saving about 20% of the protection cost. Together, thanks to the modular planning of the DC circuit breaker, the time to repair and replace components is uniformly reduced by 50%, improving the protection power.

In wind farms, the use of DC circuit breakers also greatly reduces the need for protection. The data show that after the use of DC circuit breakers, the uniform repair interval time of wind power equipment increased from 1 per year to 1 every 3 years, reducing the repair frequency by 66%. A wind farm has saved more than $150,000 a year in protection costs after introducing DC circuit breakers. In addition, the self-diagnosis function of the DC circuit breaker can monitor the status of the equipment in real time, discover and solve potential problems in time, and further reduce the fault rate and protection cost of the equipment.

Improve energy efficiency

Dc circuit breakers can reduce energy loss and improve system power in high current use. The study shows that the energy loss of the power transmission system is reduced by 15% after the installation of DC circuit breakers. For example, after a power company introduced DC circuit breakers in its transmission network, the annual energy saving was equivalent to the annual electricity consumption of 2,000 households, which significantly improved the overall energy efficiency. At the same time, the efficient disconnection capability of the DC circuit breaker ensures the stable transmission of current and reduces the energy waste caused by current fluctuations.

In solar power generation systems, the use of DC circuit breakers has also greatly improved energy efficiency. The data shows that after the installation of DC circuit breakers, the converted power of the solar power generation system has improved by 10%. For example, after the introduction of DC circuit breakers in a solar power plant, the annual rated power generation can be used by 100 households, which improves the economic efficiency of the power generation system. In addition, the DC circuit breaker can still maintain low energy loss at a voltage of up to 1500V, ensuring that the solar panels can operate efficiently under various operating conditions, and further improving the power utilization of the entire system.
