NBM-30-221-D

Overview

The Cosel USA Inc. NBM-30-221-D is a single-phase EMC/EMI power line filter rated for 30 A current and 250 VAC/VDC voltage. It features a low leakage current design with a maximum of 50 uA and a capacitance of 470 pF. The unit utilizes push-down terminals for connection and supports DIN rail mounting. This two-stage filter is intended for industrial applications requiring noise suppression.

Feature Summary

• Provides two-stage filtering for effective common mode noise reduction
• Designed for low leakage current to ensure personnel safety
• Supports DIN rail installation for flexible system integration

Applications

• Industrial machinery power conditioning
• Commercial equipment noise suppression
• Single-phase AC/DC power line protection

Procurement Notes

Verify the specific suffix 'D' indicates DIN rail mounting, as standard variants may differ in mechanical form factor. Confirm that the push-down terminal type matches your wiring requirements. Ensure the 50 uA leakage current specification meets your safety compliance standards. Cross-reference the 470 pF capacitance value against your EMI suppression needs.

Selection Notes

Select this model when a 30 A rating and 250 VAC/VDC operation are required. Choose the DIN rail variant over chassis mount if space constraints or modular assembly are priorities. Consider the low leakage characteristic for sensitive environments. Verify compatibility with existing busbar or terminal block systems before procurement.

Part Context

This component belongs to the Cosel NB series of power line filters. It shares the 30 A current rating with other models like the NBM-30-101-D but differs in capacitance and leakage specifications. The series provides standardized solutions for single-phase noise filtering across various industrial sectors.
