Overview
The Cosel NBH-30-471 is a single-phase, two-stage EMC/EMI power line filter designed for chassis mounting. It supports AC and DC applications with voltage ratings of 250 VAC and 250 VDC. The unit handles a continuous current rating of 30 A. Key electrical specifications include a maximum leakage current of 50 uA and an internal capacitance of 470 pF. The filter operates within a frequency range of 10 kHz to 10 MHz. Connection is achieved via screw terminals. The component weighs approximately 320 g and holds UL, CSA, DIN, VDE, and ENEC certifications.
Feature Summary
- Two-stage filtering architecture for enhanced noise suppression
- Chassis mount design with screw terminal connections
- Dual voltage compatibility for AC and DC circuits
Applications
- Industrial machinery power conditioning
- Medical equipment EMC compliance
- Telecommunications infrastructure filtering
Procurement Notes
Verify the specific datasheet version for the NBH-30-471 model to confirm mechanical dimensions and terminal configurations. Ensure that the installation environment meets the thermal requirements for a 30 A rated device. Cross-reference certification marks such as UL and VDE against local regulatory standards before integration into final assemblies.
Selection Notes
Select this component when a robust, high-current solution is required for single-phase systems. The 30 A rating distinguishes it from lower-capacity models in the NB series. Consider the chassis mounting style if panel space allows for direct hardware attachment rather than PCB integration.
Part Context
This part belongs to the Cosel NB series of power line filters. It shares architectural similarities with variants like the NBH-30-471-D, which offers DIN rail mounting options. The series provides standardized filtering solutions for various industrial and commercial power distribution needs.
Replacement Considerations
The NBH-30-471-D serves as a functional substitute with identical electrical characteristics but utilizes DIN rail mounting instead of chassis screws. Verify mechanical fitment differences before swapping.
