LX series zero-sequence current transformer is suitable for zero-sequence over-current protection and small-current grounding line selection device in AC power system, distribution line, and electrical equipment such as alternator and motor. The diameter of the cable is φ100mm～φ240mm.

The series of zero-sequence current transformers are made of imported high-quality silicon steel sheets by special process to form a toroidal core with high accuracy and accurate limiting factor. The iron core and secondary winding are vacuum casted with high quality epoxy resin. The plastic housing is moisture-proof, stable in performance and maintenance-free. It is small in size, light in weight and small in space.

LXK series with splitable core type zero sequence current transformer consists of two semi-rings, which can be installed on the connected cable easily
