Low Voltage Switchgear is used for circuits below 1000V AC or 1500V DC. It is modular, safe and reliable, and can realize on-off, protection and intelligent control. The shell is made of flame-retardant plastic or metal (such as steel plate, stainless steel), the conductive parts are copper or silver-plated copper, and the contacts are made of silver alloy to enhance conductivity. The arc extinguishing methods include air, vacuum or magnetic blowing technology. It is widely used in industry, construction, data centers, new energy and household power distribution, such as circuit breakers, contactors, distribution boxes, etc., supports overload and short-circuit protection, and can be integrated with intelligent systems.
