Электрический / Магнитные утечки на землю Автоматические выключатели

Conforming to VDE 0664,IEC61008 standards, these breakers are applicable for use with AC 50 / 60Hz, 240V single phase or 415V three phase circuits for industrial and mining enterprises, trade buildings, and commercial and household use.To prevent accidents caused by personal electric shock from leakage of electrical wires, this ELCB is a current-operated, fast leakage protector of pure electromagnetic type, which can rapidly break off faulty circuits in order to avoid occurrence of accidents.Precise in structure and with less elements, these breakers don't need auxiliary power, and have high working reliability. Meanwhile, the switch'sfunction won't be influenced by the surrounding temperature or lightning.The mutual inductor of this item is used to test vector differential valves of passing current, and produce relevant output power for adding to the tripper in the secondary winding. If the current of the vector differential value of the protected circuit is up to or exceeding the leakage operating current, the tripper will act to cut off. This ensures effective shock rotection. **Electric / Magnetic Earth Leakage Circuit Breakers: Rated crrent: 16A, 25A, 32A, 40A, 63A, 100A (30MA/100MA/300MA); Pole: 2Pole, 4Pole:
