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.
