NBH-30-432

Overview

The Cosel NBH-30-432 is a single-phase, two-stage power line filter designed for AC and DC applications. It features a rated voltage of 250 VAC and 250 VDC with a current rating of 30 A. The unit incorporates a ground capacitance of 4.3 nF, resulting in a maximum leakage current of 500 uA. Operating within a frequency range of 10 kHz to 10 MHz, it utilizes screw-type terminals for connection. The device supports chassis mounting and holds UL, CSA, DIN, VDE, and ENEC compliance certifications.

Feature Summary

• Two-stage filtering configuration for enhanced noise suppression
• High withstand voltage capability up to 4000 VAC
• Spring-loaded captive push-down terminal design for secure connections

Applications

• Industrial equipment requiring EMC/EMI mitigation
• Power supply input stages for AC and DC systems
• Chassis-mounted electronic enclosures

Procurement Notes

Verify the specific suffix code against official Cosel documentation to confirm terminal type and capacitance values. Ensure the procurement specification matches the required leakage current limits and certification standards for the target market. Confirm chassis mounting dimensions and terminal torque specifications prior to integration.

Selection Notes

Select this component when a single-phase, two-stage filter is required for 30 A circuits operating at 250 VAC or 250 VDC. Consider the 4.3 nF ground capacitance impact on system leakage current. Verify that the chassis mount style and screw terminal interface align with the mechanical design constraints of the application enclosure.

Part Context

This model belongs to the Cosel NB series of power line filters. The series offers various configurations with different current ratings and capacitance codes. The NBH-30-432 specifically denotes the 30 A rating and the 4.3 nF capacitance variant within the two-stage architecture.

Replacement Considerations

Consult Cosel datasheets for direct substitutes within the NB series. Verify compatibility of mounting holes and terminal pitch when considering alternative manufacturers.
