The device has an accuracy class of 1 and a rated power of 10 VA. Designed for DIN rail mounting, it operates within a frequency range of 50 Hz to 60 Hz. Physical dimensions include a height of 110 mm, length of 85 mm, and width of 31 mm. The unit weighs 250 g and utilizes screw termination. Operating temperatures range from -25°C to +40°C.

Feature Summary

• Window-type construction for non-intrusive conductor insertion
• DIN rail mounting style for standard panel integration
• Screw terminal connections for secure wiring
• Class 1 accuracy for precise measurement applications

Applications

• Industrial production facility monitoring
• Renewable energy system tracking
• Infrastructure power distribution management
• Complex device connection automation

Procurement Notes

Verify availability status carefully as this item may be temporarily out of stock or restricted in certain regions. Confirm that the required operating temperature range of -25°C to +40°C aligns with your installation environment. Ensure the 750 A primary current rating matches the load being monitored. Check that the 5 A secondary output is compatible with your downstream metering or control equipment input specifications before finalizing the order.

Selection Notes

Select this model when a 750 A primary current rating is required for AC systems. The 5 A secondary output necessitates compatible receiving devices. The 10 VA rated power must support the connected burden. Consider the 52 mm bore size to ensure the target conductor fits through the window. Verify that DIN rail mounting is feasible within the enclosure design. The Class 1 accuracy suits general industrial measurement needs rather than high-precision metrology.
