Solar DC Circuit Breaker

Selecting the appropriate solar DC circuit breaker is crucial for the safety and longevity of photovoltaic systems. Our circuit breakers are designed for precise overcurrent protection in DC applications, featuring a rated current range from 1A to 63A. They are available in 1P, 2P, 3P, and 4P configurations to accommodate diverse system architectures, including those with rated voltages up to 1500V DC. The support for B, C, and D tripping curves allows for tailored protection based on the specific load characteristics and fault current levels of the installation.

These breakers are built for durability, offering an electrical and mechanical life of 20000 cycles, ensuring long-term reliability in demanding environments. With an IP20 degree of protection, they are suitable for installation within enclosures, protecting against solid foreign objects. The convenient DIN-rail mounting simplifies installation and integration into existing solar combiner boxes or distribution boards. Our products are certified to CE, CB, and RoHS standards, affirming their quality and compliance for target markets across Asia, Europe, South America, Africa, and Oceania. When specifying components for new installations or system upgrades, consider our solar DC circuit breakers for their adherence to international standards and consistent performance.
