 Origin China
 Model Number Low Voltage Current Transformer
 Brand Name TUANJ

There have 5 series of low votage current transformer as below:
(1) DP split core current transformer
Split core current transformers DP series:
The DP series of current transformers have been especially designed to facilitate their installation in new or already existing networks. Thanks to its split core they may be installed without opening any cable or bus bar circuit.
The connection of conventional CTs usually requires the interruption of the primary side circuit to pass cables or bus bars through the transformer core or to connect such cables to the primary terminals. The DP series transformers core may be easily opened and they may be installed and connected without any supply interruption, thus saving time and installation costs.
The main features of DP transformers are:
-Small size and easy mounting
-Wide inner window, allowing clamping of big cables or bus bars
-Wide range of sizes to accomodate all the existing installations
-High accuracy and reliability
Primary current: 100A-5000A
Secondary current: 5A, 1A
Standard approval: IEC44-1, BS7626
Maximum voltage: 0.72/3kV
Frequency: 50/60Hz
Rated load: 1VA-30VA
Class: 0.5, 1.0, 3.0
Short-time thermal current: Ith=100×?n
Rated security coefficient: FS<5

(2) 0.5KV Class Current Transformer (MSQ):
Specifications:
1) AC circuit
2) Rated voltage: Below 0.66kV
3) Frequency: 50Hz
4) Tests, controls, displays and records electrical equipment operation
5) Protects equipment against circuit damage.

(3) MES CURRENT TRANSFORMERS:
The MES series of current transformer have beautiful outline and Convenient for mounting in many ways. The most current transform need the special mounting and the MES series used the mounting of DIN typing With a lot of times. The protective cover for the terminal block used the switching device with Safety and quick.
