Advantages

This current transformer offers exceptional measurement accuracy, adhering to the 0.5 class standard, which is essential for precise energy metering and system diagnostics. Its durable construction ensures long-term stability and performance in demanding industrial environments. The design facilitates easy installation on busbars, reducing downtime during setup and maintenance while providing consistent signal transformation for connected metering and protection relays.

Suitable for

• Industrial power monitoring systems
• Energy management and sub-metering
• Electrical protection equipment
• Current measurement in low-voltage distribution boards

When it may not be suitable

This device is not intended for high-voltage applications or environments where the primary current exceeds the specified 800A rating. It is also not suitable for installations requiring non-standard busbar dimensions that do not fit the 86/60 mm opening.

Key specifications

• Primary current: 800A
• Secondary current: 5A
• Accuracy class: 0.5
• Busbar opening: 86/60 mm

How to use

Installation should be performed by qualified electrical personnel. The transformer is mounted directly onto the busbar through the provided opening. Ensure that the primary conductor is centered within the aperture for optimal accuracy. Connect the secondary terminals to the corresponding metering or protection device using appropriate wiring, ensuring that the polarity is correctly observed to prevent measurement errors.

What to consider before purchase

• Verify that the primary current of your system does not exceed 800A.
• Ensure the busbar dimensions are compatible with the 86/60 mm opening.
• Confirm that the secondary output of 5A is compatible with your existing metering or protection equipment.

Usage recommendations

Always ensure that the secondary circuit is connected to a load or short-circuited before energizing the primary conductor to prevent the generation of dangerous high voltages.
