China Miniature DC Circuit Breaker Manufacturers, Suppliers, Factory

The video showcases the creation process of the handle part for our circuit breaker, LQB1-125Z. This not only highlights CNLonQcom's commitment to product quality but also allows customers to view and understand the product's functionality and design from various perspectives in a novel way. Moving forward, we will progressively release more 3D models of our products, including isolator switches, combiner boxes, solar connectors, and surge protectors, aiming to offer a comprehensive product experience platform. Through these 3D models, customers will be able to understand each product's specific applications and advantages more clearly.

A solar circuit breaker switch is a specialized electrical device designed to protect solar power systems from overloads, short circuits, and other electrical faults.

Against this backdrop, our range of products, including PV switch-disconnectors, combiner boxes, circuit breakers, surge protectors, and solar connectors, emerges as key solutions. Our PV switch-disconnectors and combiner boxes not only enhance system safety and efficiency but also reduce installation and maintenance costs through innovative design. Our circuit breakers and surge protectors provide outstanding system protection, preventing electrical failures and damage, while our solar connectors offer unmatched connection reliability, ensuring long-term stable operation of the system.

1.Packaging Display: The video begins by showing the packaging process of the LD-40 2P 1000V Solar DC Surge Protector, ensuring that each product is well-protected during transportation. 2.Module Voltage Testing: Through rigorous voltage testing, the product is shown to function normally at voltages as high as 1300V, far exceeding the rated voltage requirement of 1000V. 3.Internal Chip Display: The video details the internal thickened chips of the surge protector, enhancing the product's durability and stability, ensuring long-term reliable operation. 4.Replacing Surge Protectors in Combiner Boxes: The video also demonstrates how to replace the surge protectors in the combiner boxes, showcasing the product's ease of maintenance and efficiency. The surge protector parameters are 1000V, 20-40KA, with CE certification, and the housing is made of PC flame-retardant material, providing excellent protection.

A fuse is an electrical component used for circuit protection whose core function is to automatically fuse when the current exceeds the rated value, cutting off the circuit and thereby preventing equipment damage or fire risk. The fuse is usually composed of a metal fuse (or fuse) and an insulating shell, and when the current is abnormally high, the fuse melts due to overheating and breaks the circuit.

The system's working principle is as follows: • Energy Collection: Solar panels capture sunlight and convert it into DC. • Energy Integration and Conversion: DC current is centralized through the combiner box and converted into AC by the inverter. • Safety Assurance: Isolator switches, circuit breakers, and surge protectors guarantee operational safety and system stability. • Energy Storage and Management: The battery protection box ensures safe battery charging and discharging for effective energy management.
