Miniaturized design: The product is miniaturized in size, which can meet customers' personalized requirements for the installation dimensions of the product.
Uniform dimensions: Under the same shell frame grade, the installation dimensions of products with different breaking capabilities (S, H, R) and different functions (thermomagnetic fixed type, thermomagnetic adjustable type, electronic type) are exactly the same.
