The disconnection type CT module enables testing of electrical parameters on both exchange and distribution sides by inserting a test plug without disconnecting jumper wires or cables from the termination module.

Module housing is constructed with imported GE PBT and ABS (UL94V-0) materials, using only new raw materials rather than recycled content to ensure optimal performance and reliability.
