Suitable for

• Industrial power distribution networks
• Electrical energy metering systems
• Current monitoring in large-scale electrical panels
• Signal conversion for protection relays

This device may not be suitable for low-current applications where a 1000/1A ratio would result in insufficient signal resolution. It is also not intended for use in environments exceeding its specified thermal or mechanical ratings, or in residential settings where smaller, specialized sensors are typically required.

Key specifications

• Transformation ratio: 1000/1A
• Aperture dimensions: 80x120mm
• Width: 160 mm
• Depth: 210 mm
• Height: 65 mm

How to use

Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The primary conductor must be passed through the 80x120mm aperture of the transformer. Ensure that the primary current flow direction matches the orientation indicated on the device. Connect the secondary terminals to the corresponding inputs of your metering or monitoring equipment using appropriately sized wiring to minimize signal loss. Verify all connections for tightness and proper insulation before energizing the system.

What to consider before purchase

• Ensure the 1000/1A ratio matches the requirements of your connected metering device.
• Verify that the physical dimensions of the busbar or cable fit within the 80x120mm aperture.
• Confirm that the physical footprint of 160x210x65mm is compatible with your installation space.

Usage recommendations: Regularly inspect the transformer connections for signs of oxidation or looseness to maintain measurement accuracy. Avoid exposing the device to extreme moisture or corrosive environments to ensure its operational lifespan.
