Current transformer CT 2000/5 A 127x38 412147

Current transformer – precise measurement and installation protection

The CT 2000/5 A current transformer is a component dedicated to measuring current in electrical circuits, as well as protecting against the effects of overloads and short circuits. The device is used in both industrial and commercial installations where high measurement accuracy and reliable protection are required.

Construction and application

The CT transformer converts a high primary current (2000 A) into a lower, safe secondary current (5 A), which can be used by meters, protective relays or monitoring systems. This allows for safe and precise monitoring of network load. Accuracy class 0.5 guarantees the reliability of measurements, which is crucial in billing and control applications. This model is designed to operate as a protective current transformer.

• Touch protection: The design ensures safe use, minimizing the risk of accidental contact with live parts.
• High apparent power: The rated secondary apparent power of 15 VA allows connection of various measuring and protective devices.
• FS 5 surge factor: Allows short-term loading of the transformer with a current five times higher than the rated current, which increases its resistance to current surges.
• Screw connection: Provides a secure and durable connection of the secondary circuit wires.

Construction features and compliance with standards

The CT 2000/5 A transformer is characterized by a solid construction and legalization, which confirms its compliance with applicable standards and regulations. Power consumption at 15 W indicates efficient energy use. The device does not have a copper busbar, which affects its compact dimensions (127x38 mm). Legalization of the transformer guarantees the accuracy of measurements accepted by control authorities – particularly important in billing applications.
