NBM-20-000-D

Overview

The NBM-20-000-D is a single-phase EMC/EMI line filter manufactured by Cosel USA, Inc. It supports AC and DC voltages up to 250 VAC/VDC with a rated current of 20 A. The unit features a two-stage filtering configuration designed for chassis or DIN rail mounting. Electrical connections are made via spring-loaded push-down terminals. The component operates within a temperature range of -40°C to 85°C and holds cURus and VDE certifications.

Feature Summary

• Two-stage filtering architecture provides enhanced noise attenuation capabilities
• Spring-loaded captive push-down terminal blocks enable rapid wiring without tools
• Dual certification from cURus and VDE ensures compliance with international safety standards

Applications

• Industrial machinery power conditioning
• Medical equipment EMI suppression
• General purpose AC/DC power line filtering

Procurement Notes

Verify the specific part number against official Cosel documentation to confirm terminal type and voltage ratings. Ensure the application environment falls within the specified operating temperature range. Confirm that the required leakage current specifications align with system safety requirements before procurement.

Selection Notes

Select this model when a single-phase solution is required for circuits operating at 250 VAC or VDC. The 20 A rating suits moderate power applications. Verify that the physical dimensions fit the designated DIN rail or chassis space. Consider the low leakage current characteristics if sensitive patient contact or strict safety isolation is involved.

Part Context

This component belongs to the NB series of power line filters from Cosel. The series includes variants with different current ratings and terminal styles. The NBM-20-000-D specifically denotes the 20 A variant with push-down terminals and DIN rail compatibility options.

Replacement Considerations

Direct substitutes include other NBM-20 series variants such as NBM-20-101 or NBM-20-331-D, provided the leakage current and capacitance values meet the specific circuit requirements. Verify mechanical mounting compatibility.
