The shell is made of PA66 flame-retardant shell. The product is resistant to high temperatures and can be used in an environment of -35℃ to +70℃. It can also effectively prevent fires caused by short circuits or overloads.

The internal copper fittings have good conductivity and switching ability, and thickened coils are used, worry-free short-circuit protection, and quick response. The contact points of the product are made of silver points, which are anti-oxidation, giving the product a longer service life. The mechanical life of the product can reach 9700 times, and it will not be damaged even if used frequently. The arc extinguishing cover of the product adopts a 13-frame DC special arc extinguishing cover. The product has high-performance arc extinguishing technology. The product can be stably disconnected under high current and high voltage conditions. The product's breaking capacity can reach 6KA, avoiding the risk of arcing.

The 10MMX10MM rust-proof terminal block can easily handle wiring cables of various specifications.The product protection level is IP20, and the card slot on the back of the product is a 35MM international standard guide rail card slot, which can be easily installed in the power distribution equipment.

The product has its own indicator window, which can not only serve as a safety warning, but also remind users to repair the fault in time.

Our products have many advantages over products on the market. Our products have a more competitive advantage in quality than those of our peers. We use silver with a purity of more than 95%. The purity of the cheaper silver on the market is often less than 65%. We use 13-frame arc extinguishing hoods, which have better arc extinguishing effect compared to the 9-frame arc extinguishing hoods on the market. The circuit breaker with copper inside has a longer service life and conductivity than that of brass. The product adopts the internal structure of L7, with more stable performance and stronger breaking capacity.

The standard A ratings of the SN7 series circuit breakers are 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A. The regular voltages are 1P 250V, 2P 500V, 3P 750V, 4P 1000V. Both voltage and current can be customized. Product color and product logo can also be customized.
