The device features a single-stage filtering design utilizing terminal block termination for electrical connections. It is designed for DIN rail mounting, ensuring secure installation in industrial control panels. The unit operates within a temperature range of -40°C to 85°C. Leakage current specifications are documented at maximum values of 75.5 uA and 150 uA under specific test conditions.

Power Line Filter Modules Feature Summary

• Single-stage EMI/EMC noise attenuation for single-phase power lines
• DIN rail mounting configuration for standardized panel integration
• Terminal block termination style for secure wiring connections
• Wide operating temperature range suitable for industrial environments

Power Line Filter Modules Applications

• Industrial automation control systems requiring EMI suppression
• Power supply input stages for sensitive electronic equipment
• DIN rail mounted distribution boards needing common mode noise filtration
• Medical or laboratory instrumentation power conditioning

Power Line Filter Modules Procurement Notes

Verify the exact suffix designation when ordering, as variants such as NAH-06-681-D exist with identical core specifications but potentially different packaging or minor mechanical distinctions. Confirm that the terminal block interface matches existing wiring harnesses. Ensure the 6A current rating aligns with the circuit load requirements. Check for RoHS compliance documentation if environmental regulations apply to the deployment site. Validate the voltage rating against the actual system potential to prevent insulation breakdown.

Power Line Filter Modules Selection Notes

Select this component when single-phase noise reduction is required for circuits operating at 250V or lower. The 6A capacity suits moderate load applications where space constraints favor DIN rail mounting over chassis installation. Consider the leakage current limits if connecting to sensitive ground-referenced equipment. The wide temperature range allows deployment in uncontrolled industrial settings without derating concerns. Ensure the terminal block type accommodates the wire gauge used in the target assembly.
