Thermal Magnetic 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, are used in power 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 and undervoltage protection for motors. The product has the characteristics of small size, high breaking rate, short arcing, etc. It can be installed vertically or horizontally.
