People have put forward higher and higher requirements for the performance of control and protection electrical equipment used in large-scale solar photovoltaic power plants.

When the power of a photovoltaic power plant exceeds a certain level, circuit breakers or isolating switches are required, especially for the protection and isolation of inverters, which puts forward new requirements for low-voltage components.

To this end, our company has developed a new generation of SJKM5DC(PV) series DC circuit breakers specifically for photovoltaic applications based on our original photovoltaic DC circuit breakers.

The SJKM5DC(PV) series DC circuit breakers (hereinafter referred to as circuit breakers) are used in DC grid circuits with rated voltages of DC250V - DC1500V and rated operating currents of 63A - 800A.

These circuit breakers have overload long-time delay and short-circuit instantaneous protection functions, and are used to distribute electrical energy and protect lines and power supply equipment from overload, short-circuit and other fault hazards. Normal Working Conditions: 1.

Altitude: The installation site shall not exceed 2000 meters above sea level. 2. Ambient Temperature: The ambient temperature shall not exceed +50°C and shall not be lower than -5°C. (Derating is required above +40°C, subject to consultation with the manufacturer.) 3.

Atmospheric Conditions: At an ambient temperature of 40°C, the relative humidity shall not exceed 50%. Higher relative humidity is allowed at lower temperatures, such as 90% at 20°C, with consideration given to condensation on the product surface due to temperature changes. 4. Pollution Degree: Level 3. 5.

Installation Category: III. 6. Magnetic Field: The magnetic field at the installation location shall not exceed 5 times the geomagnetic field in any direction. 7. Medium Conditions: The equipment shall be installed in a non-explosive medium without gases or conductive dust that can corrode metal or damage insulation.

8. Environmental Protection: The installation location shall be protected from wind, snow, and erosion. Company Profile FAQ Could I have prices of your produets? Welcome. Pls feel free to send us an size and Pantone Code of the logo. What's the lead time for regular order?

7-15 days for order quantity Iower than 1000pc;For more quantity,usualy 20 days. Do you inspect the finished products? Yes,each step of production and fnished products will be came out inspection by QC department before shipping. Packaging & Shipping Packaging Please ., Ltd.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
