Current transformer with openable core 1600-5A class 0.5 TO-1600-5

Current transformer for precise measurements

This current transformer with an openable core, with a ratio of 1600/5A and accuracy class 0.5, is a reliable tool for safe and precise current measurement. It is designed to work with monitoring and measuring devices, allowing proportional reduction of large currents to values acceptable by these devices. The design with an openable core facilitates mounting and dismounting without the need to disconnect the secondary circuit.

Construction and application

The transformer operates on the principle of electromagnetic induction. The conductor with the measured current flows through the hole in the core, generating a secondary current proportional to the primary current. This solution finds wide application in energy consumption monitoring systems, overload protection, and in laboratories and electrical workshops. Thanks to the accuracy class of 0.5, it ensures reliable measurement results even under high loads.

Key features and benefits

• Openable core: Allows easy mounting and dismounting of the transformer without interrupting the secondary circuit – saving time and increasing safety during installation and servicing.
