NBH-30-221

Overview

The Cosel USA, Inc. NBH-30-221 is a single-phase EMC/EMI power line filter module designed for chassis or DIN rail mounting. It features a two-stage configuration to provide effective noise suppression in general-purpose applications. The unit supports AC voltages up to 250V and DC voltages up to 250V, with a continuous current rating of 30A. It operates within a temperature range of -40°C to 85°C and utilizes terminal block termination for secure electrical connections.

Feature Summary

• Two-stage filtering architecture for enhanced electromagnetic interference suppression
• Supports both AC and DC input voltage environments
• Compatible with chassis and DIN rail installation methods
• Rated for high current loads up to 30 amperes

Applications

• General-purpose industrial equipment requiring EMI noise reduction
• Power distribution systems operating at 250V AC or DC
• Control panels utilizing DIN rail mounting infrastructure

Procurement Notes

Verify the specific ordering suffix when sourcing replacements. The base model NBH-30-221 may have variants such as NBH-30-221-D which indicate different certifications or configurations. Confirm that the required termination style matches the terminal block type specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a robust two-stage filter is needed for 30A circuits. Ensure the application environment stays within the -40°C to 85°C operational limit. Verify that the mounting solution supports either chassis or DIN rail formats. Check if additional certifications like VDE or cURus are required for the target market compliance.

Part Context

This part belongs to the NBH series of power line filters from Cosel USA, Inc. It shares design similarities with related models like the NAM-30-221 but is distinct in its specific certification and mounting options. The series is engineered for reliable performance in demanding electrical environments requiring strict EMI control.

Replacement Considerations

The NBH-30-221-D is a confirmed variant within the same product family. When replacing, ensure the substitute maintains the 30A current rating and 250V voltage limits. Verify that the physical dimensions and terminal block spacing match the existing panel layout.
