D Series Split-core Type CT for Outdoor Waterproof, Puncture&Power Harvester and Temperature Measurement
Product characteristic
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 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.

Output lead description:
1. The input end is a cable through the core (P1 → P2)
2. The output end is led out with a five core shielded wire;
3. Red represents the voltage measurement terminal; Yellow and white are temperature sensors;
4. Green and black represent the secondary current signal output;
5. Define the polarity correspondence between "P1" and the green line as the end with the same name (*)
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;
Use a torgue wrench (electric /pneumatic ) when tightening the screws and set the torque to a reasonable range .
