## Long description

The FF TP-150-5 is a professional three-phase current transformer engineered for precise electrical current measurement in industrial and commercial power distribution systems. Featuring a robust closed core design, this component ensures high accuracy and stability when monitoring electrical loads. It is specifically calibrated for a transformation ratio of 150/5A and provides a rated power of 2.5VA, making it an essential element for energy management and system protection.
Advantages
This current transformer stands out due to its reliable closed core construction, which minimizes magnetic losses and enhances measurement precision. Its compact design allows for efficient installation within electrical cabinets and distribution boards. By converting high primary currents into manageable secondary signals, it facilitates the safe and accurate operation of connected measuring instruments and protection relays, ensuring long-term durability in demanding electrical environments.
Suitable for
Industrial power monitoring systems
Commercial electrical distribution networks
Energy management and sub-metering applications
Integration with protection relays and current measuring devices
When it may not be suitable
This device is not intended for use in high-voltage transmission lines or environments where the primary current exceeds the specified 150A limit. It is also not suitable for applications requiring an open-core or split-core design for installation without disconnecting primary conductors.
Key specifications
Transformation ratio: 150/5A
Rated power: 2.5VA
Core type: Closed core
Phase configuration: Three-phase
Dimensions: 76.5 x 74 x 80 mm
How to use
Installation must be performed by a qualified electrician in accordance with local safety regulations. The primary conductors must be passed through the apertures of the transformer. Ensure that the secondary terminals are connected to the appropriate measuring or monitoring equipment with the correct polarity. Always verify that the secondary circuit is never left open while the primary circuit is energized to prevent dangerous voltage buildup.
What to consider before purchase
Verify that the primary current of your system does not exceed 150A.
Ensure the physical dimensions of 76.5 x 74 x 80 mm are compatible with your existing electrical panel space.
Confirm that your measuring equipment is compatible with a 5A secondary output.
Usage recommendations
Always ensure that the secondary side of the current transformer is connected to a load or short-circuited before energizing the primary circuit to maintain operational safety and prevent damage to the device.
