Overview
The NBH-20-432-D is a single-phase, two-stage EMC/EMI power line filter manufactured by Cosel USA, Inc. It supports AC voltages up to 250 VAC and DC voltages up to 250 VDC with a continuous current rating of 20 A. The unit features screw terminal connections for secure wiring and is designed for DIN rail mounting. It operates within a frequency range of 10 kHz to 10 MHz and includes a leakage current specification of 500 µA. The component holds UL, CSA, DIN, VDE, and ENEC certifications.
Feature Summary
- Two-stage filtering architecture for enhanced noise suppression
- DIN rail mounting style for standardized panel integration
- Screw terminal termination for robust electrical connection
- Multi-regulatory compliance including UL, CSA, VDE, and ENEC
Applications
- Industrial machinery power input stages
- Medical equipment power supplies
- Commercial IT infrastructure power distribution
- Automated manufacturing control systems
Procurement Notes
Verify the specific suffix 'D' indicates DIN rail mounting compatibility as distinct from chassis mount variants in the NBH series. Confirm that the 20 A rating aligns with your system's peak load requirements. Ensure the 250 VAC/VDC voltage limits are sufficient for your local grid or DC bus specifications. Check for RoHS3 compliance status if required by your procurement policy.
Selection Notes
Select this model when DIN rail installation is preferred over chassis mounting. The 20 A current capacity suits high-power single-phase applications. Verify that the two-stage design meets your specific EMI attenuation requirements compared to single-stage alternatives. Ensure the screw terminal type matches your existing wiring harnesses or busbar configurations.
Part Context
This component belongs to the Cosel NBH series of power line filters. The series offers various current ratings and mounting options. The NBH-20-432-D specifically denotes the 20 A variant with DIN rail mounting capability. It is part of a broader family designed for industrial and commercial EMC compliance.
Replacement Considerations
Direct substitutes include other NBH series models with identical 20 A ratings and DIN rail mounting, such as NBH-20-432 if the mounting style difference is acceptable. Cross-reference pinouts and terminal spacing with alternative manufacturers' DIN rail filters to ensure mechanical compatibility.
