Current transformer CTR-30 800/5 CL.0,5 004805515

Current transformer for control and measurement systems

The CTR-30 800/5 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 solid construction and high accuracy make it an ideal solution for both professional installers and end-users who require stable and reliable current measurement.

Construction features and application

A through-type transformer with a 30.5 mm diameter aperture, designed to work with circuits with a rated primary current of 800 A. The 800/5 ratio provides a secondary output current of 5 A with a load of up to 15 VA. Accuracy class 0.5 guarantees precise measurements, which is crucial in applications requiring high data reliability. Use in measurement systems allows monitoring of energy consumption, network load analysis, and optimization of electrical device operation.

Advantages and benefits

• Versatility: Possibility of direct mounting on a current rail or mounting plate thanks to the included brackets.
• Safety: The housing made of polycarbonate with fiberglass (flame retardancy UL 94V-0) provides protection against mechanical damage and environmental influences.
• Convenient installation: The set includes connection terminals with a cover (IP20) and brackets for universal connection of wires and current rails.
• Durability: Designed to operate in a wide temperature range (-20°C to +45°C).
• Short-circuit resistance: Withstands dynamic short-circuit current at the level of 2.5 x I_th and thermal short-circuit current (I_th) equal to 75 x I_n.
• Insulation class E: Ensures safe operation in installations with a system voltage of up to 720 V and a frequency of 50/60 Hz.
• Weight: Low weight (0.365 kg) facilitates transport and installation.

Additionally, an adapter for mounting on a TH rail (option) is available, which increases installation flexibility. CTR transformers are also characterized by high quality workmanship and durability, which translates into a long service life and trouble-free operation.
