คุณสมบัติของตัวตัดวงจรกระแสตรง

● The operating mechanism has fast closing and fast breaking functions

● The installation of the moving and static contacts in the contact arc extinguishing system is based on the principle of parallel conductors. The H-type static contacts can be repelled, which is conducive to rapid breaking at high currents. High arc resistance is installed around the moving and static contacts. Components made of materials are conducive to rapid arc closing;

● Compact structure and small size

● Thermal magnetic, leakage, DC, intelligent unified dimensions

● Attachment independent installation unit, users only need to open the attachment cover to install and replace the attachment;

● Mechanical and electrical interlocks can be installed between two circuit breakers;

● Zero or short arcing, safe and reliable operation

● Easy to use, users can install on site

● Maintenance-free life is up to 10,000 times, including 3,000 times of electrical life and 7,000 times of mechanical life.
