Comparison of AC and DC charging methods
The main types of charging for electric vehicles (EVs) are alternating current (AC) and direct current (DC), which differ in terms of efficiency, speed, and impact on the grid. The following is a deta
• Short circuit protection, overload protection
• High breaking capacity, up to 6kA
• No positive and negative poles, can be reversed, easy to connect
• Rated working current to 63A
• Opening distance>9mm, quickly cut off the arc
• Labyrinth arc interrupter
• U-shaped magnetic blowing structure, improve the ability of disaster arc
• 7 rivets ensure wiring reliability
• Busbar design, reliable and beautiful wiring
• Unique shape design
• DC products with complete accessories, photovoltaic and energy storage systems
