Current Sensors Procurement Notes

Verify the specific output configuration required, as the CR4460 series supports both voltage and current outputs. Confirm that the 24V DC power supply matches your system requirements. Ensure the solid core design fits within the available space, as it requires threading the conductor through the window rather than clamping around it. Check compliance with UL 61010B-1 and IEC 61010-1 standards if regulatory adherence is mandatory for your installation.

Current Sensors Selection Notes

Select this model when precise RMS AC current monitoring is needed for single-phase applications up to 30A. The solid core construction ensures durability and consistent performance compared to split-core alternatives. Consider the 4-20mADC output if long-distance signal transmission is required to minimize noise interference. Verify that the operating temperature range of 0°C to 60°C aligns with your environmental conditions.
