NBH-20-471-D

Overview

The NBH-20-471-D is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It supports a current rating of 20 A and operates with voltages up to 250 V AC or DC. The device features a two-stage filtering configuration designed for effective noise suppression across the frequency range of 10 kHz to 10 MHz. It utilizes screw terminals for connection and is intended for DIN rail mounting. The unit withstands voltage up to 4000 VAC and includes a ground capacitor code -471.

Feature Summary

Two-stage EMC/EMI filtering architecture
Spring-loaded captive push-down terminals
DIN rail mounting capability
High dielectric strength insulation

Applications

Industrial control systems
Power supply input stages
EMC compliance in electronic equipment

Procurement Notes

Verify the specific ground capacitor code suffix matches the required attenuation profile. Confirm terminal type compatibility with existing wiring infrastructure. Ensure DIN rail dimensions align with panel layout constraints. Cross-reference datasheet specifications for thermal derating requirements under continuous load conditions.

Selection Notes

Select this model when high-current filtering at 20 A is required within a compact form factor. The two-stage design offers superior attenuation compared to single-stage alternatives. Consider the push-down terminal mechanism for rapid installation and maintenance. Evaluate space availability for DIN rail integration in the target enclosure.

Part Context

This component belongs to the NBH series of power line filter modules from Cosel USA, Inc. The series provides various current ratings and voltage configurations for industrial applications. The NBH-20-471-D specifically addresses high-current needs with enhanced filtering capabilities.

Replacement Considerations

Direct substitutes include other NBH series variants with matching current and voltage ratings. Verify terminal compatibility and mounting style before substitution. Consult manufacturer documentation for equivalent part numbers with similar electrical characteristics.
