Electronic Circuit Breaker with rated insulation voltage up to 690V (630 frame 1000V, suitable for AC 50Hz), rated working voltage 400V, and rated working current up to 630A for distribution network circuits. They are used to distribute electric energy and protect lines and power equipment from losses caused by overload, short circuit, undervoltage and other faults. They can also be used as infrequent starting and overload/short circuit, undervoltage protection for motors. This product has the characteristics of small size, high breaking rate, short arcing, etc. It can be installed vertically or horizontally. The difference from KETKM6 products is that this product is electronic tripping.
