Current transformer CTR-30 200/5 CL.0.5 004805508

Current transformer for control and measurement systems.

Current transformer CTR-30 200/5 CL.0.5 is a reliable and precise device used in control and measurement systems, network parameter analyzers, and automatic power factor correction (PFC) systems. Its design and parameters make it a key component in installations requiring accurate current measurement.

Construction and application

Through current transformer with a passage diameter of 30.5 mm, designed to work with primary currents up to 200A. The 200/5 ratio means that for a current of 200A at the input, a signal of 5A will be obtained at the output – which is a standard in many measurement systems. The rated apparent power of 5 VA ensures stable and accurate operation of the device. Accuracy class 0.5 guarantees high measurement accuracy, which is particularly important in applications requiring certification and compliance with standards.

Key features and benefits

• Measurement accuracy: Accuracy class 0.5 ensures reliable measurement results, minimizing the risk of errors in readings and analyses.
• Versatility: The transformer can be used in both new and modernized measurement systems.
• Safety: The housing made of polycarbonate with fiberglass (flame retardancy UL 94V-0) provides high mechanical and thermal resistance, increasing safety of use.
• Easy installation: Mounting brackets for mounting on a busbar or mounting plate are included in the set, which facilitates and speeds up installation. Additionally, connection terminals with a cover (IP20) and universal connection terminals are available.
• Durability: Designed to operate at temperatures from -20°C to +45°C, allowing it to be used in various environmental conditions.
• Short-circuit protection: Thermal short-circuit current (Ith) at the level of 68 x In and dynamic short-circuit current (Idyn) at the level of 2.5 x Ith provide effective protection against the effects of short circuits in the installation.

This transformer is a solid solution for professionals involved in electrical installations and for end-users looking for a reliable element of a measurement system. Its technical parameters and design guarantee long-term and trouble-free operation.
