Current transformer, FuPacT ISFL250/630 400/5, class 1, 5VA LV480887

Precise current measurement in FuPacT ISFL systems

The FuPacT ISFL250/630 current transformer is a professional measurement solution designed specifically for FuPacT ISFL fuse-switch disconnectors. This class 1 current transformer with a power of 5 VA ensures accurate measurements in high-capacity electrical installations.

The device features a 400/5A ratio, making it ideal for industrial applications requiring precise monitoring of flowing current. Thanks to the snap-on mounting, installation is fast and seamless, while finger-safe protection guarantees full operational safety.

Design and mounting

The compact design with dimensions of 78×60×30 mm was designed with the FuPacT ISFL modular system in mind. Thanks to the standardized interface, the device works with all types of measuring devices in the range.

Snap-on mounting enables quick installation without the need for additional tools. The design does not require extra installation space - the transformer integrates directly with the disconnector, simplifying switchboard design.

Technical parameters and advantages

The transformer operates in accuracy class 1, providing high measurement precision for measuring and control applications. The accuracy limit factor FS 5 guarantees resistance to short-term overloads.

The apparent power of 5 VA at a rated voltage of 800V AC (50/60Hz) allows for stable operation across a wide range of loads. The device is factory-calibrated, eliminating the need for additional configuration during installation.

Compliance and operating conditions

The transformer meets the requirements of international standards: IEC 60044-1, VDE 0414, and BS 7626, confirming its high build quality and operational reliability.

The device operates in temperatures from -25°C to +70°C, and the storage temperature ranges from -40°C to +80°C. The IP20 protection rating provides basic protection against finger contact and access to hazardous parts.
