D Series Split-core Type CT for Outdoor Waterproof Double Puncture&Power Harvester
Product characteristic
Double puncture to take electricity ,double fixing clips to fix cables, stable and reliable voltage signal collection; open and close structure, easy to install on site and easy to operate. Quick and easy installation or removal without disconnecting the primary cable under test ,effective for safe and easy current testing ;
All manual operation parts are insulators, which can be operated live and can be branched at any position of the cable .
The appearance is double splicing color and the installation direction and phase difference can be judged by color (A-phase –yellow ,B phase –green, C phase –red )
The shell adopts ultrasonic fusion welding integrated molding process, and the magnetic core winding structure is cast with epoxy resin and the waterproof level can be IP66.
Adopt high magnetic ，good linearity and high sensitivity.
Application
Electrical fire monitoring system ,fire equipment power monitoring system ,intelligent power consumption system, intelligent low-voltage power grid, small current grounding system, relay protection ,motor protection system, etc. For current measurement, monitoring and protection of lines and equipment.

Dimensions
Output lead description:
1. The input end is a cable through the core (P1 → P2);
2. The output end is led out by a three core sheathed wire;
3. The red wire core is the voltage measurement terminal (led out by two puncture needles);
4. Yellow and brown lines represent secondary current signal output;
5. Define the polarity correspondence between "P1" and the yellow line as the Siming end (*)
Installation precautions
When the transformer is powered on ,you must wear insulating gloves and your hands must not directly touch the red core of the shielded wire;
Before the silicon steel core is closed ,ensure that the end face of the incision is clean ,free of stains and impurities; It must be treated with anti-rust agent;
