NBH-20-000-D

Overview

The NBH-20-000-D is a single-phase common mode noise filter from the Cosel NB series, rated for 250 VAC and 250 VDC with a continuous current capacity of 20 A. Designed for DIN rail mounting via screw terminals, it operates within a frequency range of 10 kHz to 10 MHz. The unit features a leakage current of 380 µA and an internal capacitance of 3.2 nF. It complies with RoHS standards and is supplied in bulk packaging.

Feature Summary

• Provides common mode noise filtering for AC and DC power lines
• Supports DIN rail installation using screw terminal connections
• Operates effectively across a wide frequency spectrum from 10 kHz to 10 MHz

Applications

• Industrial control systems requiring EMI suppression
• Power distribution units needing line noise reduction
• Electronic equipment protection against electromagnetic interference

Procurement Notes

Verify that the specific application voltage does not exceed 250 VAC or 250 VDC limits. Confirm that the operating current remains below the 20 A rating to ensure safe operation. Check that the required leakage current tolerance accommodates the specified 380 µA value. Ensure physical space allows for DIN rail mounting and screw terminal access. Validate compatibility with the target frequency range of 10 kHz to 10 MHz for effective noise filtration.

Selection Notes

Select this model when a 20 A current rating is required for single-phase applications. Choose based on the need for DIN rail mounting rather than chassis installation. Consider the 3.2 nF capacitance value for circuit coupling requirements. Evaluate the 380 µA leakage current against safety isolation standards. Verify that the 250 VAC/VDC rating matches the system voltage levels.

Part Context

This component belongs to the Cosel NB series of power line filters. It shares the same voltage and current ratings as the NBH-20-000 variant but differs in mounting style. The NBH designation specifically indicates DIN rail compatibility, distinguishing it from chassis-mounted alternatives like the NAM series. This series focuses on common mode noise reduction for industrial environments.

Replacement Considerations

The NBH-20-000 is a direct functional substitute for the NBH-20-000-D part number. For chassis mounting requirements, the NAM-20-000-D offers similar electrical specifications but requires different installation methods. Ensure any replacement maintains the 20 A current rating and 250 VAC/VDC voltage limits.
