As a leading enterprise in the field of circuit protection in China, LANSON's product line covers a diversified range of circuit protection devices, guided by technological innovation and segmented market demand, forming a full category layout from basic to high-end. The following is an overview of its core product categories and representative products:
1、 Basic circuit protection devices
Current fuse
Miniature fuses: including plastic square/circular fuses, ceramic patch fuses (such as NANO patch type), and ultra small fuses (such as 0402 package), suitable for high-density electronic devices such as smartphones and laptops.
Glass tube/ceramic tube fuse: There are two types: fast break type and delay type. For example, the Φ 5.2 × 20mm fast break glass fuse can quickly cut off short-circuit current, while the Φ 6.35 × 30mm delay type allows for brief overload and is suitable for scenarios such as motor start-up.
Insert/bolt type fuses: such as North American bolt type high-speed fuses and British BS88 high-speed fuses, suitable for industrial equipment and power systems.
Composite fuse: combined with resistance temperature protection function, used for overheating protection of household appliances, such as rice cookers, electric irons, etc.
Thermal fuse: easy to fuse metal temperature sensing type and organic temperature sensing type, in accordance with the national standard GB/T 9816 series, suitable for circuit protection in high temperature environments.
