NBH-30-432-D

Overview

The NBH-30-432-D is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It supports AC voltages up to 250 VAC and DC voltages up to 250 VDC with a rated current of 30 A. The device features a two-stage filtering configuration designed for common mode noise suppression within the 10 kHz to 10 MHz frequency range. It utilizes a 4.3 nF capacitance value and offers a maximum leakage current of 0.5 mA or 1.0 mA depending on specific test conditions. The unit is certified by UL, CSA, DIN, VDE, and ENEC.

Feature Summary

• Two-stage filtering architecture for enhanced electromagnetic interference suppression
• DIN rail mounting style for standardized industrial panel integration
• Screw terminal connections for secure electrical interface
• Multi-regulatory compliance including UL, CSA, VDE, and ENEC certifications

Applications

• Industrial control systems requiring EMI/RFI mitigation
• Power supply input stages for sensitive electronic equipment
• Machinery protection against conducted noise in factory environments
• Medical device power interfaces meeting strict safety standards

Procurement Notes

Verify that the specific order matches the -D suffix indicating DIN rail mounting, as non-D variants use chassis mount terminals. Confirm the required leakage current specification aligns with system safety limits, as values may vary between 0.5 mA and 1.0 mA based on application testing. Ensure the operating environment temperature falls within the specified range to maintain certification validity. Cross-reference the latest datasheet for any updates to compliance documentation before finalizing procurement.

Selection Notes

Select this component when DIN rail installation is preferred over chassis mounting for space-constrained enclosures. The 30 A rating suits high-power applications where significant current handling is required alongside noise filtration. Consider the 4.3 nF capacitance value for balancing attenuation performance against leakage current constraints. Verify that the screw terminal type meets the wiring gauge requirements of the connected power lines to ensure reliable contact resistance.

Part Context

This model belongs to the NBH series of power line filters from Cosel USA, Inc., designed for robust industrial and commercial applications. The series provides various current ratings and mounting options to accommodate diverse system architectures. The NBH-30-432-D specifically addresses the need for high-current filtering with standardized DIN rail compatibility, distinguishing it from lower-current or differently mounted counterparts in the same product family.

Replacement Considerations

Direct substitutes include other NBH series models with identical 30 A ratings but different mounting styles, such as NBH-30-432, if chassis mounting is acceptable. Verify that alternative parts maintain the same 250 VAC/VDC voltage ratings and 4.3 nF capacitance to ensure equivalent filtering characteristics. Check for compatible terminal types and physical dimensions to guarantee mechanical fit within existing DIN rail assemblies.
