Internal Specifications

INT.AUT.3VA 630A 4P 110KA ETU3 LSI L/T

This appears to be a list of internal specifications for an electrical component or system. Without further context, it is difficult to provide a precise translation and interpretation. Here's a possible breakdown based on common abbreviations in the electrical field: * **INT:** Internal * **AUT:** Automatic (possibly referring to automatic operation) * **3VA:** Could refer to voltage or amperage rating * **630A:** Likely an amperage rating * **4P:** Four poles * **110KA:** Possibly a short-circuit current rating (kA = kiloamperes) * **ETU3:** Unknown, could be a model number or internal designation * **LSI:** Likely stands for "Low Side Isolation" * **L/T:** Likely stands for "Life Time" Let me know if you have any additional context about this specification. This would help in providing a more accurate translation and explanation.
