Current transformer 50/5a 22, class 1 TI-50-5

Current transformer for precise measurements

This current transformer, with a ratio of 50/5A and a core diameter of 22 mm, is a reliable tool for measuring current in electrical installations. Designed for both professional installers and end-users, it provides accurate and safe conversion of high currents to values suitable for measuring devices. Its robust construction and compliance with IEC 60044-1 ensure long-lasting and trouble-free operation.

Construction and application

The transformer is of the through type with a closed core, which means that the conductor with the measured current passes through its central opening. This solution allows for non-invasive current measurement without the need to interrupt the circuit. The 50/5A ratio means that a primary current of 50A is converted to a secondary current of 5A, allowing it to be safely and accurately read by meters and control systems. Accuracy class 1 ensures high measurement reliability.

Key features and benefits

• Accuracy: Accuracy class 1 guarantees precise measurements, essential in demanding applications.
• Safety: Touch protection minimizes the risk of accidental electric shock.
• Versatility: The possibility of mounting on panels and busbars increases installation flexibility.
• Durability: Robust construction ensures long-lasting and reliable operation in various environmental conditions (operating temperature -5°C to 40°C).
• Easy installation: Secondary circuit connection via screw connection facilitates quick and secure connection of wires (screw terminals 4 mm²).
• Compliance with standards: Meets the requirements of IEC 60044-1, confirming its quality and safety.
• FS 5 rated current 5: Allows for momentary exceeding of the rated current without damaging the device – important when starting motors or other devices with high starting current.
• Rated power 2.5 VA: Ensures stable operation with various measuring devices.

Remember to exercise extreme caution when working with a current transformer – disconnecting the secondary circuit while the device is operating is prohibited! It is also recommended to use wires with a diameter of at least 2.5 mm² to connect the secondary circuit and to ground the S2 terminal to ensure maximum safety.
