Current transformer CT 250/5 A diameter 32 / 40.5 x 10.5 412123

Current transformer for precise measurements

Current transformer CT 250/5 A is an indispensable element in measurement systems, providing safe and accurate load monitoring. The device is designed to work with circuits with a primary current of up to 250A, converting it into a safe secondary signal of 5A, which can be read by meters and control systems. The transformer's design ensures high measurement accuracy, confirmed by accuracy class 0.5.

Construction and application

The CT 250/5 A transformer is widely used in electrical installations of commercial and industrial buildings, as well as in energy consumption monitoring systems. Its compact dimensions (core diameter 32 mm, hole width and height 32 mm) allow for installation in limited spaces. Made of high-quality materials, it ensures reliable operation even in harsh conditions. The connection of the secondary circuit is realized by means of a screw connection, which facilitates installation and ensures a secure electrical connection.

Key features and benefits

• High accuracy: Accuracy class 0.5 guarantees precise current measurements, which is crucial for the proper operation of protection and control systems.
• Safety: Rated primary current of 250 A and FS 5 current ratio provide protection against overloads and short circuits.
• Calibration: The transformer is calibrated, which confirms its compliance with applicable standards and enables its use in billing applications.
• Touch protection: The housing with touch protection minimizes the risk of electric shock during operation and maintenance.
• Low power consumption: Power consumption at 3 W allows for efficient energy use in the measurement system.
• Versatility: Designed for use in both new and modernized installations.
• Solid construction: Absence of a copper busbar simplifies installation and reduces installation costs.

The CT 250/5 A transformer is an investment in reliable and precise current measurement, which translates into the safety and efficiency of the entire electrical installation. It is a product recommended for both professional installers and users looking for proven solutions in the field of energy consumption monitoring.
