Baoding MingRui Optoelectronics Technology Co.,Ltd

When circuit grounding, CT could sense zero sequence grounding current. Equipped with relay protector or signal devices, it helps device components act for the purpose of protecting or monitoring circuit. MRD-L series zero sequence CT is a kind of cable type, using ABS engineering plastics as casing, poured by resin. With beautiful appearance, good hermeticness, high insulation, high sensitivity, good linearity, easy installation and wide application, it is not only suitable to magnetic relay, but also to electronics and micro computer devices. CT type is determined by the operation way of user. (Neutral ground, unground ground by high resistance, low resistance or arc suppression coil) MRD-L series zero sequence CT core is made of ZH120-130 cold rolled silicon steel sheet imported from Japan with smooth surface, constant thickness, good conductivity, and strong sensitivity to magnetizing, enabling the CT high accuracy and stability.
