ACREL 30II Current Transformer for Electrical Monitoring
ACREL 30II Current Transformer for Electrical Monitoring is designed for measuring AC current in electrical systems and assemblies. Its horizontal square-hole construction allows busbars and multiple cables to pass through the transformer, while the transparent polycarbonate cover provides visibility of the secondary wiring. The 30II model is suitable for connection to electrical measuring instruments and is specified for systems with a rated operating voltage of 0.66 kilovolts and a frequency of 50-60 hertz.
The ACREL 30II Current Transformer for Electrical Monitoring provides an indirect method of measuring AC current in electrical installations. The conductor or busbar passes through the transformer's opening, allowing the current to be monitored by a connected measuring instrument.
The 30II model uses a horizontal square-hole configuration. According to Acrel, the design can accommodate 1 to 2 busbars and can also be used with multiple cables. A transparent polycarbonate cover allows the secondary wiring to be viewed clearly, while the manufacturer describes the construction as convenient for wiring.
How it works
- The primary conductor or busbar passes through the current transformer's opening.
- Current flowing through the primary conductor induces a proportional current in the secondary circuit.
- The secondary output can be connected to suitable electrical measuring equipment.
- The transformer provides electrical current measurement without requiring the measuring instrument to carry the full primary current.
Why choose this product
- Designed specifically for AC current measurement in electrical systems.
- Horizontal square-hole construction accommodates busbars and multiple cables.
