4NC5923-5LT21 Siemens Current Transformer

Accessory H-rail mounting for 4NC51

The 4NC5923-5LT21 Siemens Current Transformer is a current conversion device, which has the dual functions of current conversion and isolation. It converts the large current of the high-voltage circuit or low-voltage circuit into a low-voltage small current (generally 5A), which is supplied to the instrument and relay protection device. Blue Jay can help you get a high-quality current transformer at a low price. You can get different types such as split core or solid core current transformers.
