Current transformer 600/5A 5VA class 1 SRC06005

Current transformer for busbar systems – precise measurements and protection.

This current transformer, with a transformation ratio of 600/5A and a power rating of 5VA, is a key element in measurement and protection systems. It is used to safely and accurately convert large currents into values suitable for measuring, control and protection devices. It is an indispensable component in electrical installations where monitoring high loads is necessary.

Construction and application

The through-type current transformer, manufactured by Hager, is designed for mounting on a busbar or mounting plate. Its design allows the current-carrying conductor to pass through the main opening, inducing a current in the secondary winding. This allows for safe measurement of high currents without direct contact with the high-voltage circuit. The use of current transformers enables effective monitoring of installation load, detection of overloads and provision of protection against short circuits.

Key features and benefits

• High accuracy: Accuracy class 1 guarantees precise measurements, which is important in applications requiring high data reliability.
• Safety: Galvanic isolation between the primary and secondary circuits ensures the safety of operators and measuring devices.
• Versatility: The possibility of mounting on a TS rail or mounting plate facilitates integration with various types of electrical installations.
• Solid construction: Made of high-quality materials ensures durability and reliability of the device in harsh working conditions.
• Passage diameter: The passage diameter of 20 mm allows use with wires of different thicknesses.
• Screw connection: Provides a secure and durable connection of the secondary circuit wires (cross-section 1.5 - 6 mm²).
• Touch protection: The design provides protection against accidental contact with live parts.
• FS 5 current ratio: Allows short-term exceeding of the rated current without damaging the device – useful when starting motors or other devices with high inrush current.

Technical parameters and applications

The SRC06005 transformer is characterized by a rated primary current of 600A and a secondary current of 5A. The apparent power of 5VA makes it suitable for cooperation with most standard measuring devices. Power consumption at 5.5W is typical for this type of device. The opening width of 29.5 mm and the height of 20 mm allow it to be adapted to different cable configurations. Designed to operate at temperatures from -40°C to +40°C, making it suitable for indoor and outdoor applications (with appropriate housing). The degree of protection IP10 indicates basic protection against contact with solid bodies larger than 2.5 mm – remember to provide additional protection in environments with increased risk of contact with moisture or dust.
