Designed to handle a transformation ratio of 300/5A, this device serves as a critical component in industrial power systems, enabling the safe and precise conversion of high currents into manageable signals for secondary measuring instruments such as ammeters and energy meters. With a maximum operating voltage of 720V AC, it provides robust performance in demanding electrical distribution environments.

Advantages

This three-phase current transformer offers exceptional reliability and precision in signal conversion, ensuring that energy management systems receive accurate data for monitoring and billing purposes. Its compact design facilitates efficient installation within electrical panels, while the high-quality construction guarantees long-term stability and durability under continuous operation. By accurately stepping down current levels, it protects sensitive measuring equipment from high-voltage exposure and enhances the overall safety of the electrical infrastructure.

Suitable for

• Industrial power monitoring systems
• Energy management and sub-metering applications
• Electrical distribution networks
• Integration with analog and digital ammeters

This device is not suitable for high-voltage transmission lines exceeding its rated insulation voltage. It should not be used in environments with extreme moisture or corrosive gases that could compromise the integrity of the internal windings.

Key specifications

• Transformation ratio: 300/5A
• Maximum operating voltage: 720V AC
• Phase type: Three-phase
• Application: Current measurement and signal conversion

To use the FF TP-300, the primary conductors must be passed through the designated apertures of the transformer. The secondary terminals should then be connected to the measuring instruments using appropriately sized wiring to ensure minimal signal loss. Ensure that all connections are tightened securely and that the polarity is observed according to the system wiring diagram to maintain measurement accuracy.

What to consider before purchase

• Verify that the 300/5A transformation ratio matches your specific load requirements.
• Ensure the installation space is compatible with the physical dimensions of the transformer.
• Confirm that the system voltage does not exceed the 720V AC limit.

Usage recommendations: Always ensure that the secondary circuit is never left open while the primary current is flowing, as this can lead to dangerous voltage spikes. Installation should be performed by a qualified electrician in accordance with local electrical safety regulations.
