Accurate Electrical Current Measurement
A Current Transformer (CT) is used to transform a higher primary current into a lower secondary current that can be safely measured by compatible electrical instruments. This allows meters and monitoring equipment to measure current without being directly connected to the full primary current of the electrical system.
This 50-300A/5A current transformer provides a 5A secondary output for compatible digital meters, panel meters and other electrical measuring instruments designed for a 5A CT input.
The Class 1.0 accuracy makes this CT suitable for general metering and current measurement applications. The appropriate CT ratio should be selected according to the actual electrical load and the requirements of the connected measuring instrument.
32mm Current Transformer Design
The 32 mm inner diameter provides a larger opening than smaller CT designs, making this model suitable for installations requiring additional space for the conductor or busbar.
The 32 × 10 mm busbar window can accommodate compatible busbar installations. Before selecting the product, the actual conductor or busbar dimensions should be checked against the CT opening to ensure proper installation.
The overall size of 70 × 50 × 32 mm provides a compact form factor for electrical panels and equipment where available installation space is limited.
Metering Class 1.0 CT
This product is designed as a Class 1.0 metering current transformer and can be used with compatible electrical meters and measuring instruments.
The 50–300A primary range provides multiple current options for different electrical applications. Depending on the required configuration, primary current options can include 50A, 60A, 100A, 150A, 200A, 250A and 300A, subject to availability and the selected configuration.
The 5A secondary output is commonly used with compatible panel meters, digital meters and electrical measuring systems.
Applications
The 50-300A/5A current transformer can be used for:
- Electrical control panels
- LT electrical panels
- Energy metering systems
- Power monitoring systems
- Electrical current measurement
- Distribution panels
- Industrial electrical systems
- Commercial electrical installations
- Digital panel meters
- Digital ammeters
- Energy monitoring equipment
- Electrical instrumentation
- Current monitoring applications
Suitable for Digital Meters
The 50-300A/5A Current Transformer can be used with compatible digital meters and electrical measuring instruments that require a 5A CT secondary input.
A CT allows the measuring instrument to monitor the primary current through the CT’s secondary output. This can provide a practical solution for current monitoring in electrical panels and power distribution systems.
When selecting a CT for a digital meter, make sure that the primary current ratio, 5A secondary rating, accuracy class, VA/burden requirement and physical dimensions are compatible with the meter and electrical installation.
