5A Clampon Current Transformer (Zangenstromwandler) with a 300/5 A ratio A clamp-on current sensor that provides a 5 A secondary current proportional to primary currents up to 300 A. The 300/5 A ratio makes it suitable for feeding standard 5 A current sensing inputs in measurement equipment. Key benefits - Safe, non contact current measurement with electrical isolation between the measurement circuit and the high voltage system. - Easy installation with a clamp-on design; no circuit breaks required to measure current. - Directly compatible with instruments that accept a 5 A input, such as meters, data loggers, and power analyzers. - Compact form factor that fits in tight spaces and can be installed in electrical panels, cabinets, or test setups. - Provides a straightforward, proportional 5 A output for reliable monitoring and data collection. How it works - The device is a clamp-on current transformer with a 300/5 A ratio. When current flows through the conductor inside the clamp, the secondary outputs a current of up to 5 A proportional to the primary current. Compatibility and performance - Designed to be used with current sensing inputs that accept a 5 A secondary current. - Suitable for monitoring and analyzing AC current in electrical systems, motors, loads, and distribution networks. - The ratio 300/5 A enables measurement of high currents by converting them to a manageable 5 A signal for measurement devices. Use scenarios - Energy management in electrical panels: monitor branch currents to optimize energy use and identify heavy loads. - Motor and equipment monitoring in manufacturing: track load levels, detect overloads, and help prevent motor wear. - On site testing and diagnostics: connect to data loggers or power meters to capture real time current for commissioning or maintenance tasks.
