Current Sense Transformers Procurement Notes

Verify that the required inner diameter of 0.19 inches matches the conductor size in your application. Confirm that the frequency range of 20Hz to 1kHz aligns with your system's operational requirements. Ensure the 30 Arms maximum input current capacity is sufficient for the monitored circuit. Check for UL certification E131668 compliance if safety standards are mandatory.

Current Sense Transformers Selection Notes

Select this model when a split-core solution is needed for existing wiring without disconnection. The 1:30 turns ratio determines the secondary output scaling. Consider the 5.0 Vmax RMS limit for burden resistor calculations. The wire lead style requires external termination planning compared to PCB mount alternatives.
