🔧 Construction & Operation

The TA5060 uses a through-core design, in which the primary conductor or busbar passes through the central opening of the transformer. This configuration allows current measurement without necessarily interrupting the primary conductor.

The body is fully encapsulated, providing mechanical protection, environmental resistance, and electrical insulation. The series also features tab-style output terminals, designed for quick and secure connection.

⚡ Function in the Electrical System

The component converts a high primary current into a proportional secondary current signal suitable for measurement and control circuits.

With the 100 A / 0.1 A ratio, a primary current of 100 A corresponds to the nominal secondary current of 0.1 A. The signal can be used for current measurement, monitoring, protection, and electronic control.

It is particularly suitable for systems requiring accurate current measurement, including power equipment, electrical automation, power-conversion systems, and renewable-energy equipment. BingZi documentation also indicates applications in photovoltaic, wind-power, energy-storage, and power-electronics systems.

🏭 Installation & Applications

The central through-core configuration allows use with cables, conductors, or busbars of different geometries, while the particular mounting system of the TA5060 series allows attachment to the primary conductor or a base/panel.

Possible applications:

• Power inverters and converters
• Photovoltaic systems
• Energy-storage systems
• Electrical switchboards
• Industrial equipment
• Measurement and monitoring systems
• Power automation and control
• Electrical protection systems

🛡️ Safety

The component must be installed only by qualified personnel and with the circuit properly secured.

Particular attention must be paid to the secondary circuit of the current transformer: the manufacturer specifies that the secondary must not be left open-circuit while current is flowing through the primary, and that a fuse should not be installed in the secondary circuit.

Before use, verify the transformation ratio, connections, insulation, and compatibility with the measurement circuit.

📦 Condition & Package Contents
