Summation transducer, round, 35 mm diameter HR701

Current summing transformer – precise current measurement in installations

A current transformer is a key element in measurement systems, enabling safe and accurate monitoring of large current intensities using devices with smaller ranges. Model HR701, with a diameter of 35 mm, is indispensable both in industrial applications and in commercial and residential buildings. Its construction provides galvanic isolation of the measuring circuit from the main current path, which increases safety and minimizes interference.

Characteristics and application

The HR701 transformer allows for precise measurement of currents up to 400A, converting them into a safe secondary signal of 5A. This makes it possible to use standard meters to monitor installation load, detect overloads and analyze energy consumption. The device finds application in:

• Energy monitoring systems
• Electrical switchboards
• Industrial automation
• Protection of installations against short circuits and overloads
• Measurements in laboratories and electrical workshops

Advantages and structural features

The HR701 transformer is distinguished by a solid construction and high quality of workmanship, which guarantees reliability and long-term use. The most important features include:

• High accuracy: Accuracy class 1 ensures precise measurement results.
• Galvanic isolation: Protects measuring devices and personnel from high voltage.
• Rated power 5VA: Enables operation with various types of meters.
• Wide range of operating temperatures: From -40°C to 40°C allows use in difficult environmental conditions.
• Mounting on TS rail or mounting plate: Provides installation flexibility.
• Wire cross-section: Possibility of connecting rigid wires (1.5 / 6mm²) and flexible wires (1.5 / 6mm²).
• Protection class IP10: Protection against contact with fingers.

The device was designed by the renowned company HAGER, which has enjoyed the trust of professionals in the electrical industry for years thanks to the high quality of its products and innovative solutions. Made with attention to detail, HAGER transformers provide not only measurement accuracy, but also safety and durability of the electrical installation.
