NBM-20-000

Overview

The Cosel NBM-20-000 is a single-phase power line filter rated for 250 VAC and 250 VDC with a 20 A current capacity. It features a two-stage configuration designed to withstand 4000 VAC voltage. The unit utilizes spring-loaded, captive push-down terminals for connection and supports DIN rail mounting. Physical dimensions are 2.09 x 1.62 x 3.63 inches.

Feature Summary

• Two-stage filtering architecture
• Spring-loaded captive push-down terminals
• DIN rail mounting capability

Applications

• General purpose noise filtration
• Single-phase AC/DC power conditioning

Procurement Notes

Verify the specific datasheet version for the NBM-20-000 model, as documentation may vary by region or revision date. Confirm terminal compatibility and mounting hardware requirements prior to integration. Ensure input voltage ratings match the target system's electrical specifications to prevent component failure.

Selection Notes

Select this model for applications requiring robust two-stage attenuation in a compact DIN rail form factor. The spring-loaded terminal design facilitates rapid installation and secure connections without traditional screw tools. Verify that the 20 A continuous current rating aligns with the load requirements of the protected circuit.

Part Context

This component belongs to the Cosel NBM series of power line filters. The series offers various configurations tailored for different current and leakage current requirements. The NBM-20-000 specifically addresses general-purpose needs with standard two-stage performance characteristics within the 250 VAC/VDC operational range.

Replacement Considerations

The NBH-20-432 is a comparable single-phase filter from the same manufacturer. Verify if the specific inductance values and leakage current limits of the substitute meet the original design constraints before implementation.
