NBC-30-472-D

Overview

The NBC-30-472-D is a single-phase EMC/EMI line filter manufactured by Cosel USA, Inc. It supports a rated AC voltage of 250 VAC and a rated DC voltage of 250 VDC with a continuous current capacity of 30 A. The unit features a two-stage filtering configuration designed for high attenuation of common mode noise within the frequency range of 150 kHz to 1 MHz. It utilizes terminal block connections for electrical termination and is engineered for DIN rail mounting. The device operates reliably within a temperature range of -40°C to 85°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• High attenuation performance for common mode noise between 150 kHz and 1 MHz
• DIN rail mounting design for standardized industrial installation
• Terminal block connection style for secure wiring

Applications

• Industrial power distribution systems requiring EMI suppression

• Power supply input stages for machinery operating in noisy electrical grids

Procurement Notes

Verify the specific part number NBC-30-472-D against official Cosel documentation to confirm technical specifications. Ensure compatibility with existing DIN rail infrastructure and terminal block wiring requirements. Confirm that the 30 A current rating and 250 VAC/VDC voltage ratings align with the system's operational parameters before procurement.

Selection Notes

Select this component when high current handling capability of 30 A is required alongside robust two-stage noise filtration. The DIN rail form factor suits applications needing compact, standardized mounting solutions. Verify that the terminal block interface matches the available wiring harnesses and that the operating temperature range covers the intended environmental conditions.

Part Context

This component belongs to the NBC series of power line filters from Cosel USA, Inc., which are designed for demanding industrial applications. The series offers various current ratings and stage configurations to address different electromagnetic compatibility needs. The NBC-30-472-D specifically addresses scenarios requiring higher current capacity compared to lower-rated models in the same family.

Replacement Considerations

Consult official Cosel documentation for confirmed substitute part numbers. Ensure any replacement maintains the 30 A current rating, two-stage configuration, and DIN rail mounting compatibility.
