LZZBJ9-35/250W1 Current transformer
Model and meaning

Product Overview
One of the standout features of the LZZBJ9-35/250W1 is its short-time thermal stability current ratings. The transformer is engineered to withstand various short-circuit conditions, with thermal stability ratings ranging from 2/1 kA/s to 40/4 kA/s. This range indicates the device’s ability to endure short bursts of high current without sustaining damage, ensuring that it can operate effectively even in challenging conditions. The transformer’s design allows it to handle these short-time thermal stresses, making it suitable for applications where sudden surges in current are expected.
In addition to its thermal stability, the LZZBJ9-35/250W1 also boasts impressive rated dynamic stability current capabilities. With ratings from 5 kA to 100 kA, this transformer is capable of managing significant dynamic loads. This feature is particularly beneficial in environments where electrical currents can fluctuate rapidly, such as in industrial settings or during fault conditions. The ability to maintain stability under dynamic conditions ensures that the transformer can provide accurate readings and protect the system from potential overloads or failures.
