Current transformer with openable core 150-5A class 1 TO-150-5

Current transformer with openable core – precise measurements in your installation

This current transformer with an openable core is a reliable tool for measuring current in electrical circuits. Designed for both professional installers and end-users, it provides accurate and safe readings, and its construction facilitates installation and operation. The transformer allows for converting large currents into values safe for measuring devices, which is crucial in energy monitoring and control systems.

Construction and application

The TO-150-5 current transformer is characterized by a construction with an openable core, which allows for easy mounting on existing wires without the need to disconnect them. This is particularly useful during installation upgrades or temporary measurements. The 150/5 ratio means that a primary current of 150A will be converted into a secondary current of 5A, which is a standard for most meters and measuring systems. Accuracy class 1 guarantees high measurement accuracy.

The application of the transformer includes:

• Energy consumption monitoring systems: Precise measurements allow for optimizing energy consumption and identifying potential losses.
• Electrical installation protection: Works with residual current devices and other protective devices, providing effective protection against overloads and short circuits.
• Measurements in laboratories and workshops: Ideal for precise current measurements for research and testing purposes.
• Industrial installations: An essential element in industrial control and automation systems.

Key features and benefits

• Openable core: Allows mounting without disconnecting wires – saves time and minimizes downtime.
• High accuracy (class 1): Ensures reliable measurement results, which is crucial for the proper operation of monitoring and protection systems.
• 150/5A ratio: Standard ratio value, compatible with most measuring devices available on the market.
• Safety of use: Protection against touch minimizes the risk of electric shock during operation.
• Solid construction: Made of high-quality materials, guarantees long-lasting and reliable operation in various environmental conditions (operating temperature -15°C to +50°C).
• Screw connection: Allows easy and secure connection of secondary wires (4 mm²).
• Complies with IEC 60044-1 standard: Confirms compliance with international safety and quality standards.
• Small dimensions: Compact design facilitates installation even in tight spaces (dimensions: 21 x 32 x 51 mm).

Remember to exercise extreme caution when working with energized equipment! It is recommended to ground the S2 terminal and avoid disconnecting the secondary circuit while the transformer is operating due to the possibility of high voltage.
