CNKA specializes in manufacturing DC circuit breakers for solar panels in China. Our products include essential components like the casing, operating mechanism, thermal overload protection, electromagnetic tripping, contact system, and arc system.
Our circuit breakers are uniquely designed to provide effective protection against overload and short circuits. The addition of a strong permanent magnet arc system further enhances the product's short circuit capability, achieving up to 6KA.

1.Ensure correct polarity during wiring, with power entering from the top and exiting from the bottom due to our inlet design.
2.Easy installation reduces cable usage.
3.Protects low inrush current resistive and inductive loads efficiently (5-10 times In).
4.Suitable for homes, offices, construction, and industrial use.
1.Clear visual indication with red and green lights for switch status.
2.Double-thickened handle for enhanced durability and ease of operation.
3.PC flame retardant material ensures high temperature resistance, prevents deformation, offers a smooth appearance, durability, and good anti-aging performance.
4.Top cooling design for effective heat dissipation, reducing circuit breaker overheating and associated faults.
