NBC-30-472

Overview

The NBC-30-472 is a single-phase power line filter module manufactured by Cosel USA, Inc. It features a two-stage configuration designed for high attenuation of common mode noise within the frequency range of 150 kHz to 1 MHz. The unit supports a rated current of 30 A and operates at voltages up to 250 VAC/VDC. It utilizes terminal block termination and is suitable for DIN rail mounting. The device functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides high attenuation for common mode noise in the 150 kHz to 1 MHz spectrum
• Utilizes a two-stage filter configuration for enhanced signal integrity
• Supports general-purpose applications with robust thermal performance

Applications

• General purpose power line filtering
• Industrial equipment noise suppression
• Electronic systems requiring EMI/EMI reduction

Procurement Notes

Verify the specific suffix (e.g., -D) required for your application, as it may indicate terminal style or mounting variations. Confirm that the 30A rating and 250VAC specification align with your system's electrical requirements. Ensure compatibility with DIN rail mounting infrastructure if physical installation constraints apply.

Selection Notes

Select this model when high common mode noise attenuation is required between 150 kHz and 1 MHz. The 30A current capacity suits moderate-power industrial loads. Consider the -D variant if terminal block termination is preferred over other connection methods. Verify UL1283 and CSA C22.2 No.8 approvals are necessary for your regional compliance standards.

Part Context

This component belongs to the NBC series of power line filters from Cosel USA, Inc. The series includes various current ratings and configurations. The NBC-30-472 specifically addresses the 30A requirement within the standard voltage range, offering a balance of attenuation performance and current handling for general electronic applications.

Replacement Considerations

The NBC-30-472-D is a related variant within the same series. Verify if the terminal block configuration of the -D suffix matches your wiring needs. Other NBC series models offer different current ratings but may not provide identical attenuation characteristics.
