    Split core current transformer 400A/5Ato 2000A/5A dimension


    • The primary of the current transformer should be connected in series in the current circuit to be measured, and the secondary should be operated approximately in a short-circuit state.
    • Split-core current transformer secondary circuit is not allowed to open, so please do not install fuses.
    • Split-core current transformer should be connected to the secondary circuit before connecting to the primary circuit and tightening the screws if installing with electricity.


    Split core ct 400A 5A to 2000A 5A with feature

    1. Insulation Flame-retardant Shell: Flame-retardant shell of the current transformer, in case of open flame or not ignite, insulation to prevent energization to protect the line.
    2. Imported Silicon Steel: Imported silicon steel core, strong magnetic conductivity, durable and not easy to heat, to protect the load capacity of the current transformer.
    3. Full-turn Copper Coil: Copper wires arranged in close order along the current transformer core around the uniform distribution, lower resistance, stable performance.
    4. Quality Assurance: Each core current transformer has gone through layers of calibration and inspection, and the accuracy is confirmed to be qualified before leaving the factory.

    Tips: Installation Tips for Split Core Current Transformer

    Installing a split core ct is a critical task to ensure accurate and safe current measurement. First, make sure that the power supply is disconnected. Open the split core, ease it over the cable and secure it firmly with the fastening screws. Ensure that the current transformer core is completely closed, leaving no gaps.

    Connect the output cable to the measuring device, taking care to match the polarity. Recheck the mounting firmness. Restart the power supply and monitor the system to ensure proper operation.

    After installation, check periodically to ensure that the current transformer core has not loosened to ensure accurate measurements. Always follow the specific guidelines provided by the manufacturer for installation and seek professional assistance if necessary.
