Product Name: Open-close Current Transformer
Product Model: PZCT-02

Product Overview:
The PZCT-02 Miniature Open-close Current Transformer is the smallest of its kind (with an output of 100MA) featuring an inner hole diameter of 16mm and an accuracy of ≤0.5 grade. It adopts a snap-fit structure and can be directly fixed to cables using nylon ties, making it compact, aesthetic, space-saving, and quick to install.

PZCT-02 Miniature Open-close Current Transformer (Snap-fit Type)

I. Application Range:

1. This transformer is specifically designed for use with electricity meters and can be applied to both AC 220v and 380v power supply lines.

2. The open-close transformer allows for the convenient installation of electricity meters without the need to disconnect the main power circuit.

II. Features:

1. The input coil is built-in, making the transformer small and lightweight. The snap-fit design facilitates quick and easy installation.

2. It is fully enclosed, offering excellent mechanical and environmental resistance, strong voltage isolation capabilities, and ensuring safety and reliability.

III. Operating Conditions:

1. Ambient Temperature: -40℃ to +85℃;

2. Relative Humidity: Not exceeding 90% at 40℃;

3. Operating Frequency Range: 50Hz to 60Hz;

4. Insulation Thermal Class: Class B (130℃);

5. Insulation Resistance: Greater than 1000MΩ in normal conditions;

6. Electric Strength: Capable of withstanding 1000V AC for 1 minute;

7. Flame Retardancy: Compliant with UL94-Vo standard;

8. Internal Resistance: 42Ω.

IV. Precautions:

1. The primary winding of the current transformer should be connected in series with the measured current circuit, and the secondary winding should be operated approximately in a short-circuit state.

2. The secondary circuit of the current transformer must not be open-circuited; therefore, do not install fuses.
