Current transformer – precise measurement, installation safety

The 400/5 A split-core current transformer is an indispensable element in measurement and protection systems. The device is used to transform large currents into safe and measurable values, enabling precise load monitoring and protection against short circuits and overloads. The design with a split core facilitates mounting and dismounting without the need to disconnect the secondary circuit, which is particularly important when servicing installations.

Construction and application

The split-core current transformer is designed to work with measuring devices, energy meters and protection systems. Its main task is to proportionally reduce the value of the primary current, transmitting a low-intensity signal to the control and measurement devices. This makes it possible to safely and accurately monitor the load in electrical installations. Using a current transformer allows for effective energy management and minimizing the risk of failure.

Key features and benefits

• Split core: Enables easy mounting and dismounting without interrupting the secondary circuit – saves time and increases safety during maintenance.
• Accuracy class 0.5: Ensures high measurement accuracy, which is crucial for the correct operation of monitoring and protection systems.
• Rated primary current 400 A / secondary 5 A: Optimal parameters for a wide range of applications in industrial and commercial installations.
• Touch protection: Increases user safety, minimizing the risk of electric shock.
• Legalization: Confirms compliance with applicable standards and regulations, guaranteeing the reliability of measurements for billing purposes.
• Screw connection: Provides a solid and durable connection of secondary wires (recommended cross-section 2.5 mm²).
• Rated power 1.5 VA: Suitable for most standard measuring devices.
• Solid construction: Made of high-quality materials, guarantees long-lasting and reliable operation in various environmental conditions.

Remember to ground the S2 terminal and to prohibit disconnecting the secondary circuit while the transformer is operating – this will prevent damage to the device or injury to people!
