NBM-30-331-D

Overview

The Cosel NBM-30-331-D is a single-phase power line filter designed for AC 250 VAC and DC 250 VDC applications. It supports a continuous current rating of 30 A with a maximum leakage current of 75 uA. The unit features a capacitance value of 330 pF and utilizes push-down terminals for connection. It is engineered for DIN rail mounting and complies with RoHS standards.

Feature Summary

• Low leakage current design suitable for sensitive equipment
• Two-stage EMC/EMI filtering capability
• DIN rail mounting style for industrial integration

Applications

• Industrial control systems requiring low leakage
• Medical equipment power conditioning
• Sensitive electronic instrumentation protection

Procurement Notes

Verify the specific datasheet version to confirm compliance certifications such as VDE. Ensure the installation environment accommodates the specified voltage ratings. Confirm that the push-down terminal interface matches the existing wiring infrastructure. Check for any regional regulatory requirements regarding electromagnetic compatibility standards before finalizing procurement.

Selection Notes

Select this model when a 30 A current capacity is required alongside strict leakage current limitations. The 330 pF capacitance offers a balance between noise attenuation and safety limits. Consider the DIN rail form factor for space-constrained enclosures. Compare against the NBM-30-471-D if higher capacitance is needed, or the NBM-30-221-D for lower leakage requirements.

Part Context

This component belongs to the Cosel NB series of power line filters. The series provides single-phase filtering solutions for various current ratings. The NBM-30-331-D specifically addresses applications needing moderate capacitance with high current handling capabilities in a compact DIN rail package.

Replacement Considerations
