Current transformer CT 3200/5 A 127x54 412153

Current Transformer – Precise Measurement and Installation Protection

The current transformer CT 3200/5 A is a reliable device designed for current measurement in electrical circuits and for protection against the effects of overloads and short circuits. This model, with dimensions of 127x54 mm, is widely used in both industrial installations and public utility buildings. Its construction based on proven technology ensures measurement accuracy and long-term operation.

Characteristics and Applications

The current transformer converts high primary current (up to 3200 A) into a lower, safer secondary current (5 A) suitable for measuring and protective devices. This enables precise load monitoring and effective integration with protective relays, circuit breakers, and energy meters. The 0.5 accuracy class guarantees reliable readings, which is critical in applications requiring high precision. Designed for DIN rail mounting, it offers convenient installation and seamless integration with existing electrical infrastructure.

Advantages and Benefits

• High Accuracy: 0.5 accuracy class ensures precise current measurements, translating into reliable data on energy consumption and load status.
• Wide Measurement Range: Capable of operating with primary currents up to 3200 A, making it an ideal solution for high-power installations.
• Safety: Provides galvanic isolation between the primary and secondary circuits, protecting measuring devices and personnel from high voltages.
• Robust Construction: Manufactured from high-quality materials, resistant to mechanical damage and environmental conditions.
• Easy Installation: Compact dimensions (127x54 mm) and screw-type secondary terminal connections simplify installation and integration with existing systems.
• Legalization: Certified and legalized, confirming compliance with applicable metrological standards and regulations.
• Overload Factor FS 5: Allows for short-term overloads without device damage – particularly useful during motor startups or when powering other high-inrush-load equipment.
• Apparent Power 30 VA: Ensures stable operation with various types of secondary devices.

This transformer features a rated primary current of 3200 A, a rated secondary current of 5 A, and an accuracy class of 0.5. Its rated secondary apparent power is 30 VA, with an overload factor of FS 5.

This current transformer is especially recommended for applications requiring precise energy consumption monitoring and reliable protection against overloads and short circuits – from residential installations to advanced industrial systems. Its robust construction and high manufacturing quality guarantee long-term, fault-free operation.
