Epoxy Casting Current Transformer
Model MCT Round-Type
1. Introduction
- Epoxy Cast Current Transformers are devices used to convert large currents to standard small values (1A or 5A) for metering and protection purposes in electrical systems.
- iLEC MCT is a metering current transformer used for ammeters, energy meters, and monitoring devices.
- It features high accuracy (Class 1) and operates stably under normal load conditions.
2. Features
- Solid epoxy cast, excellent insulation, moisture-proof, and dust-proof.
- High durability, safe operation.
- Compact size, easy to install in electrical cabinets.
- Stable accuracy, long service life.
- Suitable for low-voltage and medium-voltage electrical systems.
