Current transformer CTR-30 600/5 CL.0,5 004805513

Current transformer for control and measurement systems

The CTR-30 600/5 CL.0.5 current transformer is a reliable and precise device used in control and measurement systems, network parameter analyzers, and automatic power factor correction (PFC) systems. Its design ensures accurate current measurement and safe operation in various conditions. It is a key component for effective energy monitoring and management.

Construction and application

A through-type transformer with a 30.5 mm aperture diameter, designed to work with primary currents up to 600A. The 600/5 ratio means that a primary current of 600A is converted into a secondary current of 5A, enabling safe and precise measurements with standard meters. The apparent power on the secondary side is 15 VA, and the accuracy class is 0.5 – this guarantees high measurement accuracy. This makes the transformer suitable for both industrial and commercial applications.

Key features and benefits

• Versatility: Possibility of direct mounting on a busbar or mounting plate thanks to the included brackets facilitates installation in various configurations.
• Safety: The housing made of polycarbonate with fiberglass (flame retardancy UL 94V-0) provides high insulation and protection against mechanical damage.
• Convenient installation: Connection terminals with a cover (IP20) and universal connection terminals ensure safe and easy connection of wires.
• Durability: Insulation class E (120°C max) and a wide operating temperature range (-20 to +45°C) guarantee reliable operation in harsh environmental conditions.
• Short-circuit resistance: The transformer can withstand high short-circuit currents – the thermal short-circuit current (Ith) is 73 x In, and the dynamic short-circuit current (Idyn) is 2.5 x Ith, which increases the safety of the installation.
• Precision: Accuracy class CL.0.5 ensures reliable measurement results, which is crucial in energy quality control systems and billing with energy suppliers.
