Overview
The NBM-16-331-D is a single-phase power line filter from the Cosel NB series, designed for DIN rail mounting. It supports AC 250 VAC and DC 250 VDC operation with a rated current of 16 A. The unit features a low leakage current specification of 37.5 uA (max 75 uA) and includes 330 pF capacitance per phase. Termination is achieved via push-down terminals, ensuring secure connections without screws. The device weighs approximately 270 g and is packaged in bulk quantities.
Feature Summary
- Low leakage current design suitable for sensitive medical or precision equipment
- DIN rail mounting style for rapid installation in control panels
- Push-down terminal termination for tool-free wiring maintenance
Applications
- Medical imaging systems requiring strict leakage current limits
- Industrial control panels needing DIN rail EMC filtering
- Precision measurement instrumentation power supplies
Procurement Notes
Verify the specific suffix 'D' indicates the DIN rail variant with push-down terminals. Confirm voltage ratings match the target circuit's AC/DC requirements. Check RoHS compliance documentation for regulatory adherence. Ensure physical dimensions fit the available DIN rail space. Validate that the 16 A rating exceeds the maximum load current including surge margins.
Selection Notes
Select this model when low leakage current is critical, such as in patient-connected devices. Compare capacitance values against other NB series variants if higher attenuation is needed. Consider the 16 A current limit relative to the connected load. Verify compatibility with existing DIN rail profiles. Evaluate thermal performance under continuous full-load conditions.
Part Context
This component belongs to the Cosel NB series of power line filters. The series offers various current ratings and capacitance options. The NBM-16-331-D specifically targets applications requiring 16 A capacity with low leakage characteristics. It complements other NB models like NBM-20-331-D which offer higher current ratings.
Replacement Considerations
NBM-16-221-D offers similar form factor with different capacitance. NBM-20-331-D provides higher current capacity but may require larger mounting space. Verify pinout and terminal type compatibility before substitution.
