Current transformer - three-phase, rated voltage 720V AC, 400/5A TP-400-5

Current transformers – precise measurement, reliable protection

Current transformer TP-400-5 is a key element in measurement and protection systems, designed for safe and precise conversion of large currents into values suitable for control and measurement devices. This device finds application in both industrial installations and commercial and residential buildings, where accurate measurements and reliable operation are required. The closed-core design ensures stable operating parameters and resistance to interference.

Construction and application

Current transformer TP-400-5 is designed to work with three-phase circuits with a rated current of 400A. Its main task is to proportionally reduce the current value, enabling safe measurement and control of the load. This makes it possible to effectively monitor energy consumption, detect overloads and protect the installation against short circuits. Accuracy class 1 guarantees high measurement accuracy, which is particularly important in applications requiring high data reliability. Mounting on a DIN rail, panel or directly on the wire provides flexibility in choosing the installation location.
