NBH-10-432-D

Overview

The NBH-10-432-D is a single-phase, two-stage power line filter manufactured by Cosel USA, Inc. It supports AC and DC voltages up to 250 VAC and 250 VDC with a rated current of 10 A. The unit features a capacitance value of 4.3 nF and operates within a frequency range of 10 kHz to 10 MHz. Designed for chassis or DIN rail mounting, it utilizes screw or push-down terminal connections. Leakage current is specified at a maximum of 0.5 mA to 1.0 mA. The component holds UL, CSA, DIN, VDE, and ENEC compliance certifications.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• High voltage withstand capability up to 4000 VAC
• Spring-loaded captive push-down terminals for rapid installation
• Multi-regulatory certification including UL, CSA, VDE, and ENEC

Applications

• Industrial control systems requiring electromagnetic interference suppression
• Medical equipment power input stages
• Commercial machinery power conditioning
• DIN rail mounted electronic enclosures

Procurement Notes

Verify the specific suffix code against official Cosel documentation to confirm terminal type and leakage current specifications. Ensure the operating environment temperature remains within the -40°C to 85°C range. Confirm that the mounting method aligns with either chassis or DIN rail requirements as indicated in the datasheet. Cross-reference the capacitance value of 4.3 nF with circuit design constraints.

Selection Notes

Select this model when a single-phase filter with 10 A capacity is required for both AC and DC applications. The 4.3 nF capacitance and two-stage design suit environments needing significant noise reduction between 10 kHz and 10 MHz. Consider the 4000 VAC withstand rating for high-voltage isolation needs. Verify compatibility with DIN rail or chassis mounting infrastructure before procurement.

Part Context

This component belongs to the Cosel NBH series of power line filters. The series offers various configurations tailored for different current ratings and capacitance values. The NBH-10 variant specifically addresses 10 A applications. The product line emphasizes compact form factors suitable for DIN rail integration while maintaining robust electrical performance standards across multiple international safety regulations.

Replacement Considerations

Consult Cosel technical support for direct substitutes within the NBH series. Verify that any alternative maintains the 10 A rating, 250 VAC/VDC limit, and 4.3 nF capacitance. Ensure mechanical mounting dimensions and terminal types match existing infrastructure to avoid redesign.
