## Summary description

The Gossen SC40-C current transformer is designed for high voltage applications with a nominal input voltage range of 720 - 3000 V and a nominal output current of 5 A. It features a compact design with dimensions of 57.2 mm width, 49 mm depth, and 67 mm height. The transformer is CE and RoHS certified, ensuring compliance with safety and environmental standards. Its cable diameter is 2.8 cm, making it suitable for various installations.

## Long description

The Gossen SC40-C Black 5 A split-core current transformer is designed for retrofit and installation in confined or hard-to-reach locations where interrupting the conductor is impractical. It supports nominal input voltages in the 720–3000 V range and provides a nominal secondary current of 5 A. Compact dimensions (57.2 mm × 49 mm × 67 mm) and a 28 mm cable diameter allowance permit use on many cable and busbar installations. The unit is CE- and RoHS-certified and includes two UV-resistant cable ties for additional fastening.
Advantages
The split-core design allows the transformer to be clipped onto live cables without disconnecting the circuit, reducing installation time and complexity. Mechanical design features ensure safe retention of the primary conductor and produce a clear audible click when closed. The transformer supports continuous operation at rated current and short-time thermal withstand for fault conditions, and its insulation class and rated frequency match common industrial and commercial installations.
Suitable for
 Retrofit metering and monitoring on existing power lines and busbars
 Installation in tight or difficult-to-access electrical cabinets and panels
 Applications requiring 5 A secondary output for power meters, relays, or energy monitoring systems

How to use
Open the split-core housing, place the transformer around the primary cable or busbar and close until the housing audibly clicks into place to confirm secure engagement. Route the secondary leads to the measuring device or protection equipment and make the required connections to the 5 A secondary circuit following applicable wiring standards. Use the supplied UV-resistant cable ties to secure the transformer and prevent movement. Verify polarity and perform a functional test with instrumentation before placing the system into normal operation.
Usage recommendations
Install and commission the transformer in accordance with local electrical codes and safety regulations. Ensure the primary conductor fits within the specified 28 mm diameter, and avoid exposure to temperatures above the insulation class rating. For accurate measurements, place the transformer on a single conductor, avoid nearby conductors through the aperture, and periodically inspect the mechanical closure and cable ties for integrity.
