4. Structure & Components

• Metal Enclosure: Provides robust mechanical protection for internal parts and fulfills the grounding function to enhance electrical safety.
• Insulator: Normally made of ceramic or heat-sealed insulating material, which effectively prevents electric arcs and short circuits, isolating live components.
• Fuse: Built-in thermal fuse, serving as the core component to realize overcurrent and short-circuit protection, cutting off faulty circuits timely.
• Contact Sheet: Responsible for current conduction, equipped with multiple contact points to ensure low contact resistance and stable power transmission.
• Terminal: Used for busbar connection, available in bolt-type terminals or spring-loaded terminals to meet different installation demands.

6. Installation & Maintenance Recommendations

• Installation Orientation: Correctly distinguish the power bus and load bus before installation; the two are generally marked with color coding (red for power supply, blue for load).
• Fixing Method: Secure the product to the DIN rail with bolts or spring clips, ensuring tight and reliable contact to avoid poor conduction or loosening.
• Inspection Points: Regularly check the integrity of the fuse, and inspect whether the terminals are loose or oxidized to eliminate potential safety hazards.
• Replacement Operation: Conduct replacement only under power-off conditions, and verify that the rated current of the newly installed bus plug matches the system parameters to ensure operational safety.
