Current transformers are electrical devices used to measure alternating current (AC) in a circuit. They work by producing a reduced current that is proportional to the current in the primary circuit, allowing for safe measurement and monitoring. Typically made from high-quality magnetic materials, these transformers are designed to operate efficiently under various electrical loads.
| Primary current range | 5A to 5000A |
| Secondary current rating | 1A or 5A |
| Accuracy class | 0.5 to 3.0 |
| Frequency range | 50Hz to 400Hz |
| Insulation class | Class A to Class F |
When selecting a current transformer, consider the primary current rating and the required secondary output. It's essential to specify the accuracy class needed for your application, as well as the frequency range in which the transformer will operate. Additionally, check for insulation class requirements based on the installation environment. Always request a quote for the quantity you need, as bulk orders may offer cost savings.
