Product Description
The series of residual current transformer are rectangular split core type, which are designed by our R&D to meet the demand of market, and are widely used in electrical fire monitoring, intelligent power utilization and other fields. It is encapsulated with epoxy resin, which has good anti-seismic and moisture-proof. It can be directly installed without disassembling the bus-bar, they reduce the cost of installation Significantly.
