Product Information
Full details
This Socomec current transformer (MPN: 192T2010) is for electricians and system integrators needing precise current measurement in electrical systems up to 100A. Its key benefit is the accuracy class of 0.5 for reliable readings, though it requires careful installation to maintain its specifications. It offers a 100A primary to 5A secondary current ratio with 1.5VA apparent power and features a convenient through-hole design with snap fixing for easy mounting on copper rails.

FAQs
What is the maximum primary current this transformer can measure?
The maximum primary measuring current is 100A.
What is the standard secondary current output?
The secondary nominal current is 5A.
What is the accuracy class of this Socomec current transformer?
This transformer has an accuracy class of 0.5.
How is this transformer mounted?
It features snap fixing for mounting onto copper rails and is a through-hole type.
What is the opening diameter for the primary conductor?
The opening diameter is 21mm.
What is the apparent power rating of the secondary circuit?
The secondary apparent power is 1.5VA.
Can this transformer be used for primary currents higher than 100A?
No, exceeding the rated primary current can lead to inaccurate measurements and potential damage to the transformer and connected equipment.
Troubleshooting
No output current on secondary side
Verify that the primary conductor is correctly passing through the transformer opening. Ensure the secondary circuit connections are secure and the connected device is functional. Check that the primary current is within the transformer's rated range.
Inaccurate readings from connected device
Confirm the accuracy class of the transformer (0.5) meets the application's requirements. Ensure the primary conductor is centered within the opening. Check for any loose connections on the secondary side. Verify the connected device is properly calibrated and compatible with a 5A secondary current.
Transformer not securely mounted
Ensure the transformer is properly snapped onto a suitable copper rail. If using a different mounting method, verify it provides a stable and secure fit. Check the integrity of the snap-fixing mechanism.
Pros and Cons
Pros
- High accuracy (Class 0.5) for precise measurements.
- Standard 5A secondary output for broad compatibility.
- Easy installation with snap fixing and through-hole design.
- Durable construction suitable for industrial environments.
Cons
- Limited opening diameter (21mm) may not fit all conductor sizes.
- Requires proper mounting on copper rails for optimal performance.
- Apparent power of 1.5VA might be insufficient for very high-burden secondary circuits.
Setup, Compatibility & Care
Setup:
- Ensure the electrical system is de-energized before installation.
- Pass the primary conductor (cable or busbar) through the opening of the current transformer.
- Securely snap the transformer onto the appropriate copper rail using its integrated fixing mechanism.
- Connect the secondary terminals (marked 'I1' and 'I2' or similar) to the measurement or protection device.
- Ensure all connections are tight and secure.
Compatibility:
- Compatible with systems where the primary current does not exceed 100A.
- Designed for mounting on copper rails.
- Secondary output is 5A, compatible with devices requiring this standard.
- Opening diameter of 21mm suits conductors or busbars up to this size.
Care:
- Keep the transformer clean and dry. Use a dry cloth to remove dust.
- Avoid exposing the unit to corrosive atmospheres or excessive moisture.
- Periodically check connections for tightness, especially after initial installation and system startup.
