NBM-06-331

Overview

The NBM-06-331 is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It supports a current rating of 6 A and operates at voltages up to 250 VAC and 250 VDC. The device features a two-stage filtering architecture designed for effective noise suppression. It utilizes terminal block mounting for secure electrical connections.

Feature Summary

• Two-stage EMI/EMC filtering architecture
• Terminal block connection interface

Applications

• Industrial equipment power input stages
• Medical device power supplies
• Office automation machinery

Procurement Notes

Verify the specific suffix designation when ordering. The base model NBM-06-331 typically denotes terminal block mounting, whereas the NBM-06-331-D variant indicates DIN rail mounting. Confirm the required mechanical mounting style matches the application hardware before purchase to ensure physical compatibility.

Selection Notes

Select this component for applications requiring single-phase noise attenuation with a 6 A capacity. Ensure the operating voltage does not exceed 250 VAC or 250 VDC. Verify that the terminal block mounting style aligns with the available panel space and wiring infrastructure.

Part Context

This part belongs to the Cosel NBM series of power line filters. These modules are engineered for electromagnetic interference reduction in sensitive electronic systems. The series offers various current ratings and mounting options to suit different enclosure designs.

Replacement Considerations

The NBM-06-331-D serves as a mechanically compatible alternative if DIN rail mounting is preferred over terminal blocks. Both share identical electrical specifications but differ in installation method.
